I have a tronxy x8, i thinks its an Anet a8 clone...Last night I was printing something and I walked away from my printer for about 15mins and came back to it stopped and turned off. It would not turn On when I would click my power switch but it would make a ticking sound inside the power supply box and my LCD screen would just flash but turn off right away also the fan Inside the power box would turn on and turn off right away as well. This morning I tried turning it on again and my LCD screen turned on and stays on as well as the fan inside the power supply box and turns back on and stays on after I turn it off and the ticking went away BUT, now even though those thing are turning on now My LCD is just blank no numbers/letters, when i plug the printer to my computer it makes the sound that it normally makes when something is plugged to it via USB, also while having the printer plugged in, if I click connect on repetier host, it says it's connected but I can't send any commands to my printer and in the log it just shows a bunch of "?" Also, my hot end turns on and Gets hot by itself, keep in mind that I can't send any commands to my printer for the hot end to turn on I'm not sure what to do please

Also just discovered that one of the hot bed. Cables got broke from the solder
help!

TMC2100 - Nema 17 How Hot can they go

by Slanger

So running TMC2100 in mks gen 1.4 today started to get a few missing steps so, lowered print speed, still there, lowered voltage on tmc2100's, upped them to 0.91 and are a lot better could do with a little more.

The drivers themselves rarely go above 30c the motors can go up to 50c.

So how hot can one run the Nema 17s (Original Anet's)

In the link below I think I read that as 80c MAX - Temperature rise: 80°C max (rated current, 2 phases on)

Currently running all jumpers out of board, and I think in stealth mode.

Anet a8 with bowden j head running on skynet sliced by sli3er

I think that my filament is breaking in my extruder mid print as i am unable to push more filiment througn and have to use a alan key to push the remaining through...

i first thought it was my retraction going too far back, was at 3mm then 2mm then 0.5 nothing changed.

could it be my j head is a bad copy?

any help is welcome.... thanks in advance..

MKS Gen L no usb connection

by ccraig1984

So I have a MKS Gen L, I can load a bootloader and firmware with my USBasp, but it isn't recognized by the computer through usb. Also when I have the LCD12864 plugged in, I don't get anything on the screen but when I push the rotary down, it beeps and the screen flashes. No info on the screen just solid blue. The screen does work on my Biqu KFB 3.0. Any suggestions? I'm thinking the board is toast, which I'm not upset at just wanted to get my CTC Dual on Marlin instead of Sailfish.
