I've been struggling with warping on the base layers on my PLA prints. I've tried to print to blue painter's tape with the heated bed off. However, when I run the print the bed heats up regardless.
In MatterControl I'm setting the heated bed temp to 0C, exporting to an SD Card. When I load the print, the LCD on the target temp says 0. But the bed heats up to the 80C range (of note, the bed heats faster than when I heat the bed as part of print where I'm using a heated bed).
Thoughts?
Thank you

Re: Heated Bed won't shut off Rostock V3
It's quite bizarre. Does it start heating as soon as the printer does? Or does it have to be starting a print for it to do this? Perhaps it's a MOSFET going, or it may be the PID drive Min.

The bed heats up as soon as the hot end reaches temperature and drops to the bed to print.

I'm running FW Version: 0.92.2 with an HE280 hot end and an Onyx heating bed. The version of MatterControl 1.6.3.8003

I am not too familiar with MC, but could there be an option somewhere to use firmware temp instead of the temp set in the material parameters? Check if that 80C is a firmware preset.

Re: Heated Bed won't shut off Rostock V3
Could you post the first hundred lines or so of your G code?
Re: Heated Bed won't shut off Rostock V3
Check the MatterControl settings under Printer->Custom G-code->Start G-code. You may have the default code in there which sets a fixed temperature for the bed and or extruder. I suggest the following:buellrider77 wrote:The bed heats up as soon as the hot end reaches temperature and drops to the bed to print.
Start G-code
M104 S[temperature]
M190 S[bed_temperature]
M109 S[temperature]
G28
End G-code
G91
G1 Z10 E-5.0 F12000
G90
G28
M104 S0 ;turn off hotend
M140 S0 ;turn off bed
M84 ; disable motors
