I3 A Pro - Moving extruder (calibration) reboots device

Hi
I have a I3 A Pro and when trying to properly calibrate the extruder (using the 100mm method), as soon as I use the control box (not laptop but direct at the printer), to tell it to extrude more than around 20mm at a time, the box reboots/resets itself! I am running Merlin 1.1.8. Anyone else had this issue? Many thanks

I know it's been awhile since you posted, but you were not alone in this. This is one of several problems I have encountered, and determined for me it was related to just dialing the extruder, but related to moving the dial quickly in ANY setting, for example moving the Y axis too quickly, or adjust the heat too fast caused a reboot. I think it is the same version firmware that I had uploaded, but have not found a solution other than dialing SLOW>

I think you need to open the PSU box.
Then you can try to replace the a4988 of extruder

How about the default fw?Have you try to upload it and test it?

Yeah, I had first built the machine about 4 months back, and had gotten the marlin file titled "PI3A Pro(for the upgraded kit using lead screw)" from the forum at that point and uploaded successfully.
The box reboot had a been a problem I just worked around by writing g-code to extrude 100mm of filament, and calibrated off that. I am going to try to do the Marlin update again, as I am dealing with another issue (see other post, as to not hijack this one).
