Re: M2 upgraded to rev G (?) and requires new belt clamp

I modified one of these. I added the larger pad to allow for a a coarse threaded screw to be sunk horizontally to allow adjustment. This was adding the new mount to a gen 1 M2 with a Bondtech extruder and Copperhead. https://photos.smugmug.com/photos/i-fVSFmJC/0/deaaea81/S/i-fVSFmJC-S.png https://dr...

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 ...
