I connected the printer by the Repetier software V0.84 , its showing me the sentence on bottom FIRMWARE_NAME …etc
but when i trying to move any axes by manual control arrows its simply doesn’t react , i did try also extruder and bed - in program showing me that the temperature is getting up
but when i touch bed or the extruder they are still cold , its impossible that i connected every motor + bed and extruder wrong … i did follow everything carefully …
any ideas whats wrong? I also did try reset motherboard , and also i did set up the voltage . Please help .
Can be problem with ports? In device manager i have COM1 and usb COM3 , but in repetier software it can find only ports “virtual printer” and COM1 ,but COM1 is wrong and COM3 it can’t find , its connected through “virtual printer” port named in repetier.
Did you try pressing the refresh ports button?
Check that the power supply is outputting 15 volts to the control board.
Make sure you are using the USB cable that came with the printer.
You can use another one just to verify communications.
If you have it plugged in to a surge protector remove it and plug it in to the wall or a regular power strip.
In the printer settings make sure that “Reset on Connect” is set to disabled
If all else fails remove the driver and reinstall it.
yea ,so definitely something wrong with that driver , PC doesn’t want read and find even my mobile now …
going to try and find different one …
You could try doing a restore to your system… assuming it’s Windows.
You should also scan it for malware and viruses before installing the driver.
- so you was right ,thank you for advice, i just did reinstall the driver and now seems to be ok … but another problem came up …temperature on extruder showing 763 … stoped due to error
somewhere is short probably … gonna fix it… thank you again
Remove power from the printer.
Check the resistance for Therm 1 (I think that’s the extruder)
at room temp it should be around 100K
Right,
When I try to manually move my printer it comes up with the message Printer stopped due to errors. Fix the error and use M999 to restart(Temperature is reset. Set it before restarting). When I look at the commands in the log it constantly cycles through numbers then comes up with random errors. I don’t think that it should be trying to carry out commands? it is also showing that I have 3 extruders across the bottom even though I have only selected 1 extruder in printer settings.
Hi,
I found this in the FAQ & Tips section.
When you get the following error message: “Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)”
There is probably something wrong with any of the 2 thermistors (extruder and/or heated bed thermistor) as the printer goes into this state when it sees a temperature that is not sensible. Check the value of both temperatures, they should show room temperature when not heated. If they show 0°C or a really high temperature then something is wrong. First fix this error (probably wiring) and then use the manual G-Code entry in the manual control tab in Repetier to send “M999” to the printer. It will then be reset and you will be able to control the printer again.
Thanks for the reply. I’m getting the 0 reading from the extruder but when checked it’s reading about 85 ohms at the thermistor. Could it be shorting out in the body of the extruder when fitted and is there a way round this? I didn’t know about the g code thing.
Thanks
That sounds right.
You really need to check the leads coming from the thermistor.
Right, I have found the problem. It is the thermostat. Because its such a small wire and such an awkward place to put it I seem to have broken 1 of the legs off. But when I replaced with a new one and entered the M999 code in the repetier software it moved the printer to the position I asked but then came up with the same error message and extruder still reading 0. Could this be caused by the one of the wires shorting out on the block of the extruder? Did anyone else find this an awkward design and is there any other way of doing it?
measure the resistance before powering the printer (and after mounting it), so you may catch the short before it burns up. And yes, been there, done that. Twice. 
ANother, IMO easier way to fix the thermistor is using kapton tape. You still need to be careful to isolate the legs from each other and from the hotend, but its certainly easier to work with than the stock solution.
Yeah iv done it twice now but the last time I measured the legs once soldered and I got 100 but didn’t measure again once fitted. Should you get a reading of similar value when checking the connection at the board end. (Obviously not plugged in to te board)
Hi,
Since it is reading 0C this sounds more like an open now.
Remove the power from the printer.
Unplug Therm 1 and check the resistance at room temp it should be around 100K
If not check the wiring and soldering.
Well when trying to adjust the thermistor to prevent the wire from touching the housing I snapped a leg on my last thermistor so picking up another one from my local electrical store. But they won’t get any in till later today!
