Geeetech

I'm just commiserating... I've been trying to use UBL with the 3D Touch. It worked for a while, then I had a disaster and had to service the machine and after putting it all back together I had to remap the bed and it's never been the same. I've resorted to painstakingly adjusting the Z-offset and t...

It was overkill for just the printer but this is the exact kit I bought: https://www.amazon.com/gp/product/B01MC ... UTF8&psc=1

I don't exactly understand what's happened now - I an auto-tune the PID to any temp I please and it works fine.

Once tuned, the bed stalls out around 50-51 degrees until the protection kicks in again and shuts it down.

I've gone back and run the M303 E-1 S60 which worked fine. It's possible in my tinkering I broke those settings so I'll cross my fingers and see what happens.

If I set my bed to heat to 60C, it gets to about 57C and holds there until the thermal protection kicks in and shuts everything down. It will still *sometimes* get to temp but not reliably so. I assume it's a broken solder connection on the bottom of the bed but I haven't torn it down for full inspe...

My bed has stopped heating reliably and even errors out the printer if I try. I'm looking into replacements and fixes.

Aside from the official Geeetech parts, are there any other compatible beds I should consider as a potential upgrade or replacement?

As has turned into a pattern for me every time I fix something, something totally unrelated breaks. My cheap BMG clone just never was quite right, I went to replace it... Removing it eventually required drilling out a stripped set screw on my extruder motor. A $6 metal extruder from Amazon worked ok...

On my A10 heated bed I have an array of wires - 2 black 2 red 1 blue 1 green I guessed that blue/green were likely the thermistor, red was +24v and black was ground/- since that would follow standard +/- color coding. I find instead that one of the red/black pairs shows the 100k resistance expected ...

I've now added TMC2209s with sensorless homing. Important side note - recent documents suggest the TMC2209 works with spreadcycle homing but I found that not to be the case. BigTreeTech's Marlin repo defaults to explicitly setting spreadcycle homing and provides zero documentation about it which cos...

Using the below images, I cut the connector off the control-board end of the hotend bundle. I'm don't have the 3d touch connected yet but I've confirmed I've got motion control, heating and fans. I've crimped on JST connectors for leads that needed them. Pin -> Board Connection 6 -> I 7 -> H 8 -> D ...
