Errors in serial file after firmware update to 1.12

Troubleshooting
1

Hi All. I had the “one z-motor inop issue” and received new board (Thanks Bar!!!). I ran a job and had it fail part way through with a load of “position error” messages. I did not save the serial file…oops

Per other user posts, I updated firmware to 1.12, uploaded new index file, kept my .yaml file. On a fresh boot of the Maslow I see a bunch of errors and different things in the serial file that are not normal to me…I am connected to the Maslow 4.0 via WiFi.. I am hesitant to start a new job with these messages on boot up. See below for serial file from fresh boot. Please advise if I missed something.

I think that this is causing the issue. That error 3 is caused when the machine is trying to read something from the .yaml file which isn’t in there. Can you try starting with a clean .yaml file and copy over the values of your anchor points? You shouldn’t need to re-find them.

On it! Thanks for the help.

anchor points? You shouldn’t need to re-find them.

when you do a full install, it puts a maslow.yaml file on the machine, but for
at least the last couple of versions, the file it puts there isn’t working and I
have to upload a maslow.yaml file to get rid of these error messages.

I think I remember uownloading and uploading the default file and it worked
one time, but I’ve done so many flashes as part of my auto-updating development
I don’t remember for sure.

but there is something that it’s not happy with at the end of a full install.

Edited a new .yaml file and the boot up looks clean.

Noticed multiple differences in the two files.
They were (for example):

Anchor points were near the top as Maslow_tlY: 2401.800049 (for example) and the new file has them in the kinematics grouping with just tlY: 2401.800049

I also set Maslow_vertical to true and added my Maslow_Extend_Dist value as this took some time to dial in with the vertical orientation (which I am about to abandon and go flat - the maslow does not stay flat on upward motion)

axis are noted as a, b, c and d which look like individual belts vs x, y and z - interesting

acceleration_mm_per_sec2: values are 50 vs 25 in my old file

max_travel_mm values are 5000.000000 in new file vs 2438.399902

It looks like I am good to go. thanks for all the support.

I too got the ‘error 3’ message and had to start with a new YAML file

I think it’s because of the move of the frame dimension data to a new MaslowKinematics section of the yaml

Hi Maslow friends.
Here is an update. I got a chance to set up for a new cut today and one of the belts would not tension. Lower Left (as facing the unit in vertical config) motor would move slightly when I watched the windings inside the motor. I bumped retract force up to 1800 and no luck. It would retract all and extend all just fine. The serial string notes position error and recommends redo calibration. I am guessing that something may still be wrong in the edited .yaml file. I will start with a fresh .yaml file and go from scratch.

well, loaded virgin .yaml file. Went through setup and calibration, set z limit and z home. The process had some issues, but the lower left belt started working. Once calibration finished and said happy message, I was happy at this point everything was working. I can retract, extend, apply tension, move z, jog around the material. So….I decided to go for it and cut new part. Loaded the gcode file, reset home to appropriate spot on material and hit go. When the router began moving from home to start the cut at the upper right, I notice the lower two belts start to slack. They never regain tension. The router lowers to proper cut depth and begins to cut. It is a clockwise curve and when it gets about 1.5’ of cut, it gives the e-stop and that is the end. lower left and right belt are very loose. . I have the serial file if helpful.
So it looks like I have changed from one problem, through some others and now to slack belts.

It’s always good to post the serial log, that will tell us why it stops. In this
case, it’s almost certinly going to be because of the slack belts (that the
position it calculates is too far off from where it thinks it is)

So it looks like I have changed from one problem, through some others and now to slack belts.

This is probably the result of problems with calibration.

a quick checklist.

while it’s calibrating, the belts need to pull tight at each point. If they
don’t, you need to increase the calibration current limit (or fix the arms so
they pull tight with less current)

If you get poor fitness, it can be for a couple of reasons.

  1. Z height problems.

    The default maslow.yaml has Z offsets for each arm that are the distance from
    the arm to the bottom of the sled. If the arms are in a different order, these
    numbers are incorrect.

    If the anchors are not at the same height as the bottom of the sled during
    calibration, but the arms are in the correct order, you can use the
    spoilboardThickness and workpiecethickness variables in maslow.yaml to adjust
    this. It’s a good idea to use spoilboardThickness for any differnce from the top
    of the spoilboard to where the anchors are and then use workpieceThickness to
    adjust for the thickness of your workpiece while cutting.

    Note, that this Z height is not in relation to earth’s gravity, but in
    relation to the plane of the surface your sled is riding on. If you have a
    horizontal frame (on the ground) this can be a subtle source of error if your
    surface is not horizontal as far as gravity is concerned (for example, if you
    have your workpiece on the top of a bench, and then measure up from the floor
    for your anchors, if the bench is not on the same plane as the floor, your Z
    heights can be off significantly)

  2. frame flex.

    If the anchors move during calibration (i.e. a wood frame flexes) it will give
    you wrong measurements

  3. belt stretch.

    If you have to set the calibration current high to get one arm to retract (due
    to mechanical friction in that arm), the other arms can be pulling really hard
    and stretch the belt, giving wrong measurements

  4. the belt catches on something

    It’s not uncommon for the lowest belt (bottom left) to catch on things (the
    corner of the workpiece, dust collection hose, etc) and if it doesn’t get pulled
    straight, it will result in bad measurements.

  5. calibrating with too large a grid size for your frame.

    When you get too close to the edges or corners, you can have the arms hit the
    uprights on the sled. The sled will try to rotate, but if you have two arms
    hitting the uprights trying to rotate the sled in opposite directions, the belt
    will flex at the end of the arm instead and with the belt and arm not being
    right in line with each other, you get the wrong measurement.

So, with this in mind, please tell us your frame size, and the grid size you
used, and if the anchors are even with the bottom of the sled or not.

Hi Dave.

thanks for the check list. I like it

  1. I verified the order of the arms. It matches Bar’s video on youtube. My corner pins have 2” of vertical adjustment. Spoilboardthickness and workthickness variables are new to me with this version of firmware. I have a 3/4” spoilboard and 1/4” workpiece. I set the height of the bottom of the lines depending on what i have to cut. In this case, I set them at 1” up from the frame.
  2. My frame is 15 series 80/20 (i had a bunch) It is cross braced and gusseted. It also is attached to the side of my pole barn and concrete floor. The pin to pin distance is 100” high x 129” wide. The board is “vertical” with a 23.7 deg angle.
  3. Both the retract and calibration are set to 1300. I had it up to 1800 but put it back after no success when lower left belt would not tension.
  4. no snag issues with this setup and I always watch espically when retract all and apply tension. When running there are no snag points
  5. the calibration settings were the default.

Here is the serial log starting with the virgin .yaml file

It looks like I hit calibrate more than once, not sure what happened here. I only meant to hit is once…….. maybe fat fingers……..

more of a reply via email following, but with a 100x129" frame, this is the good/questionable cutting area

the black rectangle is your 4x8 plywood, wach yellow grid line is 100mm, the green bands in the yellow/orage areas are to indicate accuracy problems (each band is a 1 degree error between the belt and the arm due to arms hitting the uprights)

thanks Dave. I took a look at the heat map in the browser (click through the pages of the .gcode render) and try to position the workpiece for the most green. My project is for a high school theater set and this one is long at 80”, but only a bit gets into the gold area on corners of the 4x8 board. Keep the recommendations coming. The kids are counting on me getting these done.

  1. I verified the order of the arms. It matches Bar’s video on youtube. My
    corner pins have 2” of vertical adjustment. Spoilboardthickness and
    workthickness variables are new to me with this version of firmware. I have a
    3/4” spoilboard and 1/4” workpiece. I set the height of the bottom of the
    lines depending on what i have to cut. In this case, I set them at 1” up from
    the frame.

spoilboard and work thinkness are new, and Bar isn’t convinced they are an
absolute requiement (he has just ignored the errors produced and gotten
results that are good enough for his work)

setting the bottom of the belt end connections 1" up should work, that should
put them even with the bottom of the sled.

When you calibrate, make sure the router is all the way down against the
steppers. This both makes sure it’s square, but it sets Z zero (the lowest point
the machine can go) (forgot to mention this in the earlier post)

There is then Z home, which is where the bit is just touching the top of the
workpiece that you set when you put a bit in.

  1. My frame is 15 series 80/20 (i had a bunch) It is cross braced and
    gusseted. It also is attached to the side of my pole barn and concrete floor.
    The pin to pin distance is 100” high x 129” wide. The board is “vertical”
    with a 23.7 deg angle.

since you have adjustable anchors, make sure that they don’t flex as the machine
pulls tension on them.

  1. Both the retract and calibration are set to 1300. I had it up to 1800 but put it back after no success when lower left belt would not tension.

but you took apart the arm and fixed that, so they now tension correctly at
1300, correct?

This looks wrong, the next group should be 13 points (the outside of a 5x5 grid)
but is is only measuring two.

and why does it go back into calibrating at this point? that’s odd, the next

This is indicating a problem with the bottom left belt being off from what it’s
expecting.

This is only measuring in a 400x400 area, with your frame size, you should be
able to go much larger 1400x1000 should be safe

Maslow_calibration_grid_size: 3

set for a 7x7 grid

@bar, any thoughts?

thanks Dave. I took a look at the heat map in the browser (click through the
pages of the .gcode render) and try to position the workpiece for the most
green. My project is for a high school theater set and this one is long at
80”, but only a bit gets into the gold area on corners of the 4x8 board.
Keep the recommendations coming. The kids are counting on me getting these
done.

once you are calibrated, going out of the green will produce some distortion,
but for a setpiece, it’s unlikely to be noticable (unless there is a joint
there)

thanks for all the help Dave.
I have a 4.1 upgraded system and this all started with a new board to fix the inop Z axis. (which is fixed with the new board)

The issue with the lower left arm not tensioning was not solved with increasing the motor current. It would retract all and extend just fine like the other 3. It was only when it would do apply tension. it would not move but you could see the inside shutter or jog back and forth.

When the calibration was running, it would slack the two lower belts and move, then apply tension. It seemed kinda slow but got there.

I had a discussion with Bar on the height of the anchor points and agree that the cosine error would be small.

When it stopped the cut, both lower belts became loose. The lower right was more than the left, but it was moving right to start the cut.
I guess I find it odd that I could jog all over the board without any issues. belts all looked great.

I can wipe is again and start from scratch one more time.

Per your last note…… Not a problem for a set piece. at 30+ feet you will never notice..

One thing you might want to look at is how fast the Maslow is being asked to move in your GCode.. Too fast and it won’t spool out correctly

17

cutting speed is 200mm/min for XY and 50mm/min Z. Cutter is a Maslow 1/4” upcut bit. Material is Patriot Timber Products RevolutionPly 5mm x 4-ft x 8-ft Sanded Plywood

cutting 5mm thickness in a single pass.

That should not be a problem.

Someone else had this same issue last week and the solution was to increase the calibration grid size. The default right now is 500x500mm which doesn’t seem to be big enough. Going to something larger like 500x1000mm seems to fix that issue.

We’re working on a change which will automatically calculate the right grid size for your frame which should prevent that from happening in the future.

Thanks Bar!!! I will reset and run calibration/corner finding again with a bigger area. I will post with progress. not sure if I will get to it tomorrow.
