Hello everyone. I’m new guy here. Yesterday i whose soooo happy!! i did my first print in good quality. But…i really don’t know why, after reset i got problems with control:
- Can’t heat noozle and bed.
- Temerature of second noozle is 739 degrees!!!
- The driver does not memorize settings of temperatures.
In Repetier Host i don’t have full control. I can only do XYZ base, without steps and after i push nozzle to get heat up he is automatically turning off.
Below are screens.
Do You have any suggestions?
I will be very grateful for Your advice.
Do you have 2 print heads installed?
If you do
Check the wires for therm 2 (left print head) the middle green connectors.
It looks like you have a short on the thermistor.
If not.
You need to check the middle green connectors on the left side.
You also need to change the firmware
Yes i do, i got 2 nozzles. I’m using original firmware.
What it means, “a short on the thermistor”?
And thank You that You are trying to solve my problem. Maybe one day i can help You to : )
It looks like there is a connection between the 2 middle screw green connectors on the left side.
If you remove the wires the temp on the left should drop to 0C.
Thank You for help.
After i updated firmaware printer is working fine!
Thanks and wishing all the best.
