Re: Printed part has bad X-axis shift, generally poor print

I had read that in the eSun specs someplace and on different websites when I started with PETG. I don't use it for anything but mechanical items that need to be strong yet flexible, they are normally simple shapes. I do make a cover for a knife sharpener strop that is a single .8mm wall using the ....

Re: Slice Engineering Copperhead hot end 450C

In progress on a M2 Gen1. I just got the heater cartridge today. I need to flash the firmware for the new thermistor and rerun the hot end wires. The themsitor cartridge comes with a warning card to updrade to Marlin 2.0 or modify the 1.x firmware with lookup table values. A couple of thoughts/obser...

Re: No Heated Bed = Power Connector Fail

Thanks Ed, I appreciate the advice. I inspected the wiring on the extruder earlier this year when the connector failed at the stepper motor. It looks ok but I may take the opportunity to replace it with new wire. The HBP wiring is ok but I've got a new HBP unit that I can swap in just to be safe. I ...

No Heated Bed = Power Connector Fail

M2 Rev D purchased November 2015. Its been in climate controlled workshop or an air conditioned house since that time. The last year I've been printing 20 hrs a day 5 days a week. Primarily PETG with heated bed at 90c. The power connector positive socket has failed in a surprising way. I am looking ...

Re: Printed part has bad X-axis shift, generally poor print

Have you printed this before successfully? I had x axis shifting recently on my M2 while printing PETG. It was due to slightly over extruding and printing without a fan. The print was curling at the edges of the print and blobbing. This was catching the extruder as it went by causing skipping. I bac...

Re: PETG build surface adhesion advice

I print PETG on buildtak. First layer is definitely "smushed". If I'm worried about adhesion, I'll throw some magigoo on the buildtak. I print push plastic PETG (10KG rolls) at 255c and 90c bed. I back down the bed temp to 80 after the 3rd layer and turn the fan on. I was getting too much sagging wi...

Not sure on why you can't remove it. That's a metal collar if yours is like mine. Is it possible that the threads are galled and stuck in the collar? Can you clamp the Z and twist the know?

Would you mind sharing your Config and Config_adv files? I'd like to give the upgrade a try.

Re: How is the M3 wired to the Raspberry PI?

Thanks for that. I spoke with support yesterday. There is apparently a daughter board in the mix that is not available as an upgrade. I'm assuming its a level converter to change from 5v to 3.3v for TX/RX pins. Not sure how the 5v power is being tapped to power the PI. It appears to be powered from ...

How is the M3 wired to the Raspberry PI?

I see that the M3 has an integrated Raspberry PI for octoprint next to the Rambo board housing. It does not appear to be connected through the USB port. So how is it connected?
