BOSS Delta 300 - One Belt stops functioning

[biancosplanco]

Hi everyone, it's me again!

I was able to run a successful print on my new BOSS Delta 300 when I first got it, but I'm having an issue where one of the belts seems to stop functioning properly. I first noticed a problem when I went to run a print and the nozzle would grind into the glass on the first layer. After that issue, I emergency stopped the print & ran a Delta Calibration (G35) from the Duet Wi-Fi controller. After running the calibration smoothly, when I went to home the axes, one of the belts was no longer working when I ran a 'home' command. When I restart the machine via the power switch, I'm able to control all three belts correctly with stepping in X, Y or Z directions via the Duet Wi-fi controller, but then the one belt stops moving when I run a home command. I took a video but it's too large to add.

Other notes: the belt that isn't moving is still locked, i.e. I can't move it with my hand while the machine is on. It seems to be the "Z" tower's belt from what I understand.

Any idea on what might be causing this issue?

Delta calibration should be G32, not G35.

Can you post the contents of your homedelta.g file?

tnx.

Hi gene - see below:

; homedelta.g
G91 ; relative positioning
G1 H1 X750 Y750 Z750 F5000 ; move all towers to the high end stopping at the end-stops (first pass)
G1 H2 X-5 Y-5 Z-5 F5000 ; go down a few mm
G1 H1 X10 Y10 Z10 F500 ; move all towers up once more (second pass)
G1 Z-5 F1000 ; move down a few mm so that the nozzle can be centered
G90 ; absolute positioning

Also attached a screenshot.

The calibration is G32, my mistake. I run it from the dashboard on the Duet Wifi Control under "Compensation & Calibration"

I also noticed the X/Y aren't at 0 after homing. Not sure if that is having anything to do with the issue.

[geneb]

The X & Y values are kind of high - on my Boss 300, they're both at 0.4.

I would try deleting your config-override.g file and then re-run the calibration. If you still have the problem, post your config.g file and I'll see if I can spot an issue with it.

Hi Gene,

I was able to delete the config-override file an re-run the calibration. Now, when my machine is homed, the X is at 2.5 and the Y is at -2.5.

That said, the issue where the Z belt/tower is unable to move in positive Z direction persists. It seems to be fine moving up and down in the Z direction when I restart the machine, but after I home the printer and move the head down, the Z belt won't go back up again regardless of what direction I move the machine. It's causing issues when starting a print as well to the point of total failure.

Any idea what the issue might be? Could this be a power problem?

I don't see anything obvious - I would check to make sure that the stepper motor connection for the Z motor is firmly seated. If it is, I'd reach out to support directly.
