Re: Bed not reaching 110C

There was a cold solder joint, I am now at 3-4 ohms for the bed. After some further analysis, I determined the power supply cannot adequately heat the bed, so I am replacing it.

Input voltage for GT2560?

I have been monitoring my power supply (12V, 15A, 180W): with no load it gives 11.4V, when connected to my GT 2560 and the heaters are on (bed and extruder) voltage drops to 8.6V. Is that normal, or an indication my power supply is being over worked? Can I use a 24V, 15A, 360W power supply with the ...

Re: For people who wants STL files of parts

I am looking for the STL files for the Spider and the 2 part hot end holder that fits inside it. for the G2 mini Rostock.

Re: For people who wants STL files of parts

It is a 3 part hot end for the G2, using the heim joint rods. Thanks!

Re: Problem on 2nd print in a session (duty cycle?)

This issue appears to be resolved by adjusting the stepper motor drivers from where they were (0.8V) to 1.0

Re: Voltage recommendations for stepper drivers on G2 kit?

Thank you. I understand to adjust and check for overheating. I have them A4988 set to 1.0 V now, and the motors are not hot even after a 2 hour print.

Re: Bed not reaching 110C

I just finished zeroing everything out, so I didn't want to disassemble the bed. I unplugged the heater from the board, and measured the resistance at the solder pads 1 to 3. Would you still like a picture?

Bed not reaching 110C

Hi, I recently purchased a Geeetech G2 mini rostock kit from you. Most everything is working, But I cannot seem to get the bed to working temperature. The resistance on the bed measures 6.2 ohms, this seems too high. Can you check your specifications, and if this is out of the normal range can you p...

Voltage recommendations for stepper drivers on G2 kit?

Hi, I had a bit of trouble with my extruder jamming. I was able to solve this by adjusting the driver voltage pot unit it would extrude 50 mm abs @230 C without jamming. The voltage on that pot now shows 1.635V. Unfortunately I didn't check to see what kind of stepper driver I have here before I put...
