I accepted a request to print a Roman sculpture called the Townley Greyhounds for a friend. I kind of wish I hadn’t as I’ve spent/wasted days on it. Despite the printer producing some seriously impressive excellent quality prints, it just does not like printing this model. Lots of first layer issues like layer flow, first layer not laying down within walls... all of which suggests that it struggles with the size file (+100mb) and perhaps the complexity of the print. Even Cura takes about 5 minutes to slice it. I don’t really wish to print this direct from SD card as I don’t want the printer running at night, not supervised. At least not without the thermal cut outs and safety features of the Octoprint. Has anyone else had issues with certain prints? https://www.myminifactory.com/object/3d-print-the-townley-greyhounds-112600

Think I need to adjust that corner, although all the mounting screws are pretty dam tight. Any advice on trying to level out that corner?

Printer stops on first or 2nd layers with this error. Anyone know the cause and fix? Only seems to happen when printing from SD card

has anyone else got corrosion happening on the 2 small diodes/resistors that are attached to the underneath of the Aluminium bed? I’m getting very erratic temperatures with the thermal runaway tripping and causing the printer to shut down Mid print which I’ve put down to these Diodes.

I’ve recently upgraded to the TMC2208’s and the bed will no longer home in the centre. Looking through the marlin firmware I can see that the X & Y clearly state the old TMC1200. if upgrading to the new TMC2208’s does the firmware need to updated?

Anyone know why I'm getting such wild temperature fluctuations on my 2nd hot head? Set at 195oC and as you can see from the image it fluctuates between 187oC and 207oC which is obviously too much of a variance. Hot head 1 is working perfectly and only fluctuates ~1oC

My X & Y motors have completely stopped working (Z is fine) and I’m getting this error message: Proforge>Tools>Home>Confirm Error:Printer halted. kill() called! anyone have an idea what’s going on?

Whilst trying to cure the lines in the print, it looks like I’ve turned the pots on the 2 TMC1200’s just ever so slightly too much clockwise (Too many volts). The display disappeared. I’ve since replaced the TMC1200’s and whilst the display works, there is still no movement on the XYZ axis’. I wish I had used a DVM to properly calibrate the volts instead of doing it by eyesight as the destructions suggested. As the XYZ doesn’t work, I’m lost to how to identify if it’s the main control board, display board, or something else. Anyone have any suggestions?
