M4 v0.82 Calibration safety stop after waypoint 2

[CGDrummer]

Hi, figured I’d post a new thread since others with similar topics have not rectified my issue or are dated.

I have tried calibrating my M4 for hours with frustrating results. I am set up on my garage floor horizontal orientation with 3/8 concrete anchors. I had measured a 12’x7’ rectangle, but on inspection it looks like one anchor was incorrectly driven about 6’6" so it is asymmetrical by one corner. I had plenty of errors, so I will list them in order even though I have rectified most. at the end I will share my serial notes of last attempt.

Problem #1: belts not completely retracting. I did as instructed and released tension > retract > extend > retract. once they were finally in, my next session after reboot had 1 or 2 more not fully retracting first try. Now it seems to have sorted itself out as promised.

Problem #2: Belts not fully extending. I played around with my rough frame values in setup, but it seems as though TL and TR continually extend less than the bottom counterparts. After 2 attempts, I had enough slack to anchor.

Problem #3: fan not running. In another calibration topic, it was mentioned the fan runs when the maslow is operating, but I wasn’t seeing the fan on on the first couple tries. I manipulated the top capsule and it seems to have initiated the fan again. I checked all connections and ensured all cables were solid. No more repeats of fan issue.

Problem #4: margin errors. In another thread, it was suggested to tighten belts before calibration. Any time I did take up slack, I received an error that I was too far outside the margin and to run a calibration. However, moving directly to calibration caused an ‘unable to safely move’ error. It was around the same time as the fan issue and has since let me move straight to calibration.

Problem #5. Unable to move after waypoint 2. To be clear, I’ve verified that my setup orientation is set to horizontal with a more accurate frame size. I’ve been attempting 9x9 at 2000/1000mm. M4 starts moving, reaches waypoint 1, shows slack on 1 to 2 lines as it reaches waypoint 2, and then e-stops without any obvious binding or slippage of anchors. Rebooting this sucker has really drained my energy today…here’s the notes:

In another thread, there was questioning whether the centrepoint deviation over 30mm could be the issue and I see that my eyes weren’t lying when BL and BR have more deviation consistently. Is there an easy edit to my frame size or setup to rectify those deviations?

Is it a frame size/shape issue? Is it because I haven’t glued the ethernet cables in? Is it too much play in the anchors or waste board? I humbly wait in hopes that this is a simple thing I’ve overlooked and hoping it isn’t something bigger. I was really hoping not to have to move to a vertical setup or build a separate frame. Thanks everyone!

a 2000x1000 calibration grid on that frame size is pushing it. see
http://lang.hm/maslow/maslow4_frame.html. your frame is too wide for it’s
height. While the non-green areas aren’t indications of fatal flaws, the deeper
you go into a non-green area, the more your belt lengths will be off (which will
confuse calibration).

I would reduce the calibration grid to 2000x600 or so.

Problem #1: belts not completely retracting. I did as instructed and released
tension > retract > extend > retract. once they were finally in, my next
session after reboot had 1 or 2 more not fully retracting first try. Now it
seems to have sorted itself out as promised.

you may need to increase the retration current limit and calibraion current
limit until the belts reliably retract on the first try.

If the belts are loose during calibration (after the first few points), there is
a problem.

Problem #2: Belts not fully extending. I played around with my rough frame
values in setup, but it seems as though TL and TR continually extend less than
the bottom counterparts. After 2 attempts, I had enough slack to anchor.

if the bottom is extending more than the top, that’s an indication that you may
be in vertical mode

Problem #3: fan not running. In another calibration topic, it was mentioned
the fan runs when the maslow is operating, but I wasn’t seeing the fan on on
the first couple tries. I manipulated the top capsule and it seems to have
initiated the fan again. I checked all connections and ensured all cables were
solid. No more repeats of fan issue.

Problem #4: margin errors. In another thread, it was suggested to tighten
belts before calibration. Any time I did take up slack, I received an error
that I was too far outside the margin and to run a calibration. However,
moving directly to calibration caused an ‘unable to safely move’ error. It
was around the same time as the fan issue and has since let me move straight
to calibration.

that just requires setting the frame size larger and trying again.

Problem #5. Unable to move after waypoint 2. To be clear, I’ve verified that
my setup orientation is set to horizontal with a more accurate frame size.
I’ve been attempting 9x9 at 2000/1000mm. M4 starts moving, reaches waypoint
1, shows slack on 1 to 2 lines as it reaches waypoint 2, and then e-stops
without any obvious binding or slippage of anchors. Rebooting this sucker has
really drained my energy today…here’s the notes:

try telling it your frame size is a bit bigger and try again.

@CGDrummer

asymmetrical by one corner.

This will be a pain for calibration. I had a similar issue.

My first recommendation is to measure the distances between every anchor point, and use the larger dimension for ‘width’ and ‘height’ in the initial calibration values. Do NOT use the average value, your calibration results will suck.

Also, if those larger values are significantly more/less (more than at least 5mm) than the dimensions that calibration has arrived at so far, then you need to clear out the maslow_*** values from the maslow.yaml file in your machine and start again. One option would be to upload a new maslow.yaml file to the machine for this.

[CGDrummer]

Thanks for the replies.

I made the frame set more accurate, but I will try as you say @md8n and input the largest w/h values within 5mm and see if that works. I thought I was pretty close on the last one, but then my deviations were different: ~ -28 BL, -107BR. I wasn’t sure if it was remembering any portion of the calibration since it stopped premature.

I’m sure there’s a reason why not (my guess is calibration!!!), but for this initial setup, is it not possible for the process to be retract all > extend to 90% (pad manual extend button for larger setups) > retract belts until equal tension, with a ‘release tension/retract’ feedback loop until all belts have equal tension and extension, creating an essential centre zero from anchors, regardless of square dimensions? Then, Maslow attempts a waypoint that is easy to measure, such as half the sled size on x axis. User inputs the offset from the result (deviation from x and true distance from centre in mm) and Maslow returns to centre. This is repeated four times, one in each axis direction and then leave to calibrate and verify. Or alternatively, taking a picture that includes Maslow and four stickers or strings or squaring markers on the anchor points to estimate shape as well as inputting dimensions? Would help when dealing with portability and not always having the availability of a large squared frame.

I see the calibration and distortion now, thanks @dlang for the reference calc. I plan to put some new anchors in after the weekend closer to 10’ for height, seems to be a good. I did try to drop the area down to 800/300 and 5x5 but that didn’t get me anywhere either, wouldn’t even get 1 waypoint. I know that was a shot in the dark anyway.

I will make 1 attempt tomorrow with the smaller frame setup after resetting the yaml file and hopefully remember to update

[dlang]

you can also take a look at this topic

Maslow 4 manual configuration (onshape doc)

note that if the maslow thinks distances are X and your tape measure says they are Y, the maslow is correct (at least as far as getting good cuts are concerned) since the current calibration gives different coordinates on different runs of up to a couple of mm, that seems in the same ballpark as the errors of manually reading a tape measure, so I threw together this onshape doc that lets you enter measurements and it shows the frame and calculates the coordinates. I have you measure both diago…

where I created an onshape doc tht has you measure the distances between all the
anchors and it calculates their locations

it’s also worth remembering that the maslow assumes that the bottom two anchors
are a straight line parallel to the workpiece (I don’t know which of your
anchors is the one in the wrong position, but if it’s one of the bottom ones,
the others are in wierd positions relative to that line, so the starting
rectangle would need to be larger than you expect)

the bottom counterparts. After 2 attempts, I had enough slack to anchor.

if the bottom is extending more than the top, that’s an indication that you may
be in vertical mode

On my flat setup, the bottom belts always extend about 6" farther than the top belts. This behavior was intended for the upright mode, but it does it in flat mode as well. So in other words, this is normal. However it is always good to confirm that you are in the right mode for your frame.

[CGDrummer]

Okay so I was able to add some anchor points farther away and adjusted the frame dimensions. It took about half a dozen adjustments until I was able to get a full calibration to complete. Fitness came back as ~0.36. Attempting a second calibration immediately e-stopped, even though I changed nothing. I think I’m giving up on my garage setup and will be moving towards a full frame until the auto calibration is more accommodating to atypical setups.

I will say that I marked down my width/height tests and their respective offsets. At first I needed to decrease both to lower the offset, but at a certain point I only reduced the width, as height started making BR offset worse. Calibration ran with slack on belts just enough for them to touch the floor.

[dlang]

what frame and calibration size did you end up trying?

David Lang

[CGDrummer]

I may have found success… For the first time it has successfully calibrated 7x7 to a fitness of 0.76 iirc. One of the mid calibrations was fitness 1.16, not sure if that’s just an outlier in the average. I moved the width about 100mm shorter than I expected by the time the offset was roughly -68 for bl and br, but kept the height slightly larger than actual. So I think it’s time for a test run of gcode, see how it fares, then run with a bit. Here is the log:

A further update - I decided to do another calibration, since I found that the belt paths weren’t completely unobstructed. Once clear, my fitness went up to 0.96 final on 7x7 (1000,500).

For my first cutting test, I used a spoil board that wasn’t very flat, but easily flat by the weight of the sled. My cut failed at line 30 due to margin exceeding 0.250mm. I am attributing that to a combination of the board and sawdust buildup, since I didn’t have my shopvac set up. I am a little concerned with one anchor being near parallel/ above the motor and not allowing the sled to maintain a downward pressure while under tension. I first noticed when I added my spiral bit and returned the sled to upright. The cut itself looks cleaner than I expected and no signs of char. I’m thinking of adding a little more height to the board space

If it says in the error message that it completed to line 30, does that mean there is a way for me to input the code to resume on the same board at line 30 if I was confident everything kept its position? also, where do I change parameters if I want to allow an error margin closer to 0.5mm?

sounds fantastic.

not sure what you are referring to here.

and not allowing the sled to maintain a downward pressure while under tension.

That should not be a problem, the weight of the sled should be all you need.

Update of unfortunate events. Looks like two of my belts have flipped themselves and caught into the spool gears. I can see some damage and expect that they might be done for, looks like I’ll have to order some replacements. I’m not sure the reason for the sudden instability, since I haven’t even tried another cut and the lines were straight when retracting. What made it worse was as they retracted, the two belts must have twisted, which then flipped on the spool and tightened to a tension that I cannot wedge free. And of course this is the perfect time to misplace my Allen key.

Before this incident, the only other thing I had noticed with the spools was some slight slipping on extension. I only notice the slip once on two belts, but it happened during every extension, and seemed to be about a quarter or half inch that would pull out faster. After the first little jolt, it stays the same tension until it has finished feeding the total length. Is this a tensioning issue that needs a software fix as well so I don’t have a repeat “jam session”? Or is it the higher tension that got it wedged so tight in the first place?

Hopefully it won’t be too long before I can work backwards through the assembly guide and try to replace these spools. Given that the spool housing and belts are separate order items, is it likely that I will have to replace both the belts as well as the spool housing due to notching or the wedging of those belts? Just to be safe I’ll probably order both together…

You may not have to throw in the towel on the belts just yet. I’ve had the same thing happen. I had to take the arm apart to clear the jam, but, even with a bit of the belts being pretty chewed up, cuts still seem to run perfectly fine.
