In order to accommodate my 2 inch bit and plan to cut 2 inch thick foam board I’ve setup my anchor points locations at 4” high and shortened my frame by about 4 inches per anchor point.
I started the calibration process with the maslow on top of the 3/4inch spoilboard and on top of the 2 inches of foam for a total height of 2 3/4 inches.
Calibration was successful ( attaching maslow file ).
Issue is that when I go near the far left edge and jog maslow towards upper left corner the sled tries to dig in on the front and the back of the sled lifts about 2 inches ( it did this during calibration too ) .
Then I clicked release tension … apply tension and it says I need to recalibrate:
[MSG:INFO: Center point deviation: TL: -2.393 TR: -0.783 BL: 19.033 BR: 8.176]
[MSG:ERR: Center point deviation over 12.000mm, your coordinate system is not accurate, maybe try running calibration again?]
[MSG:INFO: Requesting state change from Taking Slack to Belts Extended]
[MSG:INFO: Succeeded]
Maslow is not ready to move.
Could not perform Jog. Belt lengths are unknown.
Using a router bit that long is putting more downwards force than normal on the router which is making it want to tip.
One possible solution would be to raise up your anchor points to keep the belts more parallel to the work. Does that seem like an option?
This is because the firmware wasn’t taking into account the extra height from the z-axis being up in the math. This bug should be fixed in the next firmware release (thank you for pointing it out before). That release is still in testing, but if you want to try it it is here: Interstitial Firmware Releases - #585 by bar
My current anchor points are at 4 in high. Which is an inch and a quarter above the sled.. I added some additional reinforcement to my anchor points to eliminate any possible flex and recalibrated. I did notice during the calibration this time that the sled lifting was much more minimal although still present.
Having the anchor points too high may be causing the tilting, it could also be the pulling forces are out of balance between the different belts. When you lift the Z axis does the digging in reduce or stay more less the same. Have you loaded the new Release from @bar?
Thanks… I haven’t tried the new release yet… the thread talking about it seemed to open up new cans of worms.
After recalibrating and running a test 2mm rectangle to align spoilboard things appear not to wheelie ( but also wasn’t out to the total edge ). I’ll try a larger rectangle closer to the edge tomorrow and post my findings.
I’ve been testing it, mostly what I have noticed as problems are also in V1.15, so it’s no worse. In V1.15 a new function was added to draw a frame around the graphical representation displayed. It was supposed to let you run the Maslow around the area affected, without cutting. It projects too far away from the object and can cause the Maslow to go outside the work area. A fix was developed but missed in the latest test update. It should be available when V1.16 is released.
