I’ve been working through setup this morning. I got to the spot where I press calibrate and the sled starting going down and went off of the spoil board. I was able to stop it, but I’m not sure where I went wrong. I followed the directions on the newest YouTube video. Any help would be much appreciated!
If your initial anchor size estimates are incorrect, this could happen.

what firmware version are you on, and did you set the frame type to vertical?

@bar I think it would be useful (at least during calibration) to have a display
that shows each belt, what it’s length is, and what mode it’s in (stationary,
retracting, feeding out, compliant)
I am wondering if some people who have the sled fall off the bottom are in
horizontal mode, and one of the top belts goes into compliant mode, so it feeds
out until the user hits stop.

I set it to vertical. I followed the standard wooden frame build and then this video: https://youtu.be/nvgfBJi9kfI?si=kjptBFBeyW1qTXjh
I appreciate your help!
Hi Jason, could you check what frame dimensions you have in the config tab/file?
And the firmware version, too.
Just to be sure, can someone please tell me what each of these is called?
ie: which one is machine width? A or C?
This should be horizontal orientation, right?
It’s relative to the M4 itself. Assuming the power cord is down, A is the width, and B is the height.

Here are my settings and what is happening.
I’m 100% sure this is user error, but I can’t figure it out.
When I press calibrate, it does this:
I’m also having issues with calibration. I go through fresh on/off, set Z axis, retract and extend belts and then I press calibrate, belts tighten and then do not move and I get the emergency stop error. I’m on v70.0. I have unplugged and retried multiple times. Any recommendations? My Maslow is ground mounted with bolts from the floor on a 3/4” piece of plywood/spoilboard.
from what Bar has been saying, this is probably due to the estimate of the frame
size being too far from reality.
David Lang
No, this is the vertical orientation. Horizontal would be flat on the floor.

Thank you for your help. The measurement is from bolt to bolt, right?

Yes, center of bolt to center of bolt.

Can you tell me what firmware version you’re running?
If you haven’t updated it yet, I strongly suggest updating to the latest 0.70 version. The calibration there was greatly improved by Bar.
You can get the files here:

I’m using a starting value of 2250 for my vertical measurement and my sled is coming 1/3 off the top and bottom of the frame during the 9x9 at the end of calibration, which seems just about perfect.
Noticed your value is a bit bigger than that and your frame looks to be the standard height like mine. Might be worth trying that value. Same for maybe dropping the starting value for the width by 100-150.
I was getting good results using 3400 and 2250 for an 8x12 instead of the more-accurate 3530 and 2386. I had the same issue as you when I was giving accurate values, so I’m still using these values even with fw 0.70.2.

Looks like that was the issue. Calibration is proceeding as expected now after updating the frame size

Thank you, everyone, for your help. I deleted and reinstall software, updated the firmware and it worked like a charm! I appreciate you all and your willingness to help!
