[BUG] x home is set to x endpoint at the end of a print #59

Closed Hoppaz closed 4 years ago

Hoppaz commented 4 years ago

I start the printer and release the motor and set the x position to the left side. After this I start a print job (chessman) via octoprint 1.3.12 on octopie 0.16.0. At the end of the job the hotend strays at the right hand side of the printed model but at the end of the plate. If I press X home (via lcd or octoprint) it will not move left. Only right and after this left to the point which seem to be the new X home. If I repeat it the next jobs are shifted to right the same way.

Please attach the start and end gcode from your slicer configuration.

looks like it does not appear printing from the sdcard - still testing

davidramiro commented 4 years ago

Probably has to do with OctoPrint then, maybe there is some setting acting up in the machine settings?

Hoppaz commented 4 years ago

I've updated octoprint but no success.

I've recognized that everything is fine without connected raspberry. If I connect it via usb cable and press "x home" on the display, the head will move about 5mm to the right. This repeats on every touch of the button. If I disconnect the usb cable again and press "x home", the head moves to the position expected.

davidramiro commented 4 years ago

Sounds more like a serial/hardware issue to me. Or maybe just something on OctoPrint's side. Nothing in this firmware changes when connecting it to a USB host. Sounds silly, but are you using the USB cable provided by Anycubic? That one is known to be of bad quality and can cause all sorts of issues.

Other than that, I will probably not be able to help you any further as I can't see how connecting an USB lead is causing the display to malfunction.

I'll close this for now, but please report back if you are able to narrow down the issue!
