I’ve got my Maslow4 fully built and I updated the firmware through the web interface.
95.25" top pin to bottom pin (2420mm)
16.5" left pin to right pin (2960mm)
I’ve set my settings to the following:
maslow_calibration_grid_width_mm_X to 2960
maslow_calibration_grid_height_mm_Y to 2420
I’ve also tried (just to see if even numbers helped)
maslow_calibration_grid_width_mm_X to 3000
maslow_calibration_grid_height_mm_Y to 2500
When calibrating I’m able to retract the belts fully and then extend the belts. When hanging on my frame my belts are about 2" shy of being able to connect to the bottom pins.
I can click “release tension” twice and connect the bottom pins
After hitting calibrate the machine tightens up the belt but fails and then proceedes to no longer have heartbeat.
I’ve done this process about 10 times I’m not sure if it just dosen’t like me releasing the tension but its the only way i can get the bottom belts connected.

I added an additional 5" to frame size with the same results.

it still dosen’t extend enough belt so i need to “release tension” in order to reach the pins
Error remains the same

just a bit more than needed to attach to the frame.
try measuring the diagonals between the anchors, it’s possible that your frame
is racked and that could be why you have trouble attaching to the anchors.
just checked my frame I’m about 150-1/4 and 150-3/4 on my diaganal from post to post so I do have about a 1/2 inch deviation but otherwise it’s pretty close.
I’m thinking something else must be going wrong though because no mater what i seem to set my frame length im always the same 2" away from being able to connect my bottom cable.
Is there a gcode command to run a single motor so I can verify I got my motors stacked correctly
You hit the nail on the head. I had updated the maslow.yaml file and forgot to change to vertical orientation. I was able to get it to calibrate and am now back in business. I did make a few mistakes on the build the biggest being I put the clamping plate on in the wrong orientation so I can’t access my lock button for the router but for now I just pulled the router out to change the bit. Thanks for your help!
Is a prompt before calibration possible? Would also do well do disambiguate vertical and horizontal from portrait and landscape at that juncture as well, since that caught a few people off.
The portrait and landscape thing caught me at first as well. Honestly the UI has a couple confusing things. It’s not bad once you understand it but for me the big thing was how you go into the setup to do extensions, retraction, then calibrate. I wish there was just one big intial setup screen for calibratiion that was step by step.
Set orientation (horizontal / vertical)
Set dimensions
retract
extend
set # of points and calibration size
calibrate
There would be a duplication of extend and tension somewhere else in the interface though. Overall, now that I’m getting the hang of it it’s not bad and makes sense just kinda gotta jump around a bit.
I’ve got in a suggestion to exactly cover this point. I’ll start having a look at the UI and UX changes required very soon (i.e. sometime this week), but I’m still bouncing around thoughts about exactly how to do the presentation so that it guides new users well, but gets out of the way of experienced users.
It’s just a quick rough-out using the online whiteboard I use for project organization, but something like this would be great to see when presented with the option to make sure people know what is being asked.
If localization is ever a thing, though, it’d be good to probably have the text not be a part of the images themselves.
