I have a marlin based printer from china. And It is printing about half the Z height it should. The setting on LCD says zsteps/mm +1600.00 when I tried m92 z3200 It went way to much almost breaking my bed before I could stop it. So… Maybe the 1600 in the display is M92 z160? One strange thing is that if I manually use the LCD menu to move Z axis like 50mm up and measure travel distance it is correct but when printing it is about half… Does anyone know what the cause could be?
Do you know what lead screw it uses?
m92 z800?
Hey my name is also Kristian (yes with k).
Well try M92 Z1600.000 and also save with M500
ye me too
mine has problems printing
@Jeremiah_Coley hmmm seams like It is similar to ballscrew M8 but not. It is not normal threads. But it is correct when using move axis command but not when printing
Well, if manual non printing moves provide correct movement then it must be a printing issue. Start by getting the printer ready to print… Up to temp, any firmware leveling, etc… Then try moving it… See if it remains correct.
If it still is not reproducing the error then it maybe a slicer issue? Try another slicer and see if the error reacurres.
i will try to pause a print and then move the z axis up and measure travel. some has had a problem of steps going to fast during print and it skipps steps so it migt not come up on moving with firmware… maybe if i make a custom Gcode which is running Z axis 50mm after printing 1 layer (basicly removing all Gcode between every layer and see if it is correct travel
What is your slicer?
@Kristian_Myklebust are you printing from an sd card? Off of some other device? Also, is this problem happening all the time or intermittently?
Happened on my latest prints… Was ok couple months ago. And I’m using cura and SD card
my 3d printer just clicks at the nozzle and stops feeding filament properly? any ideas
Google clogged nozzle and u should get many tips on how to unclog the nozzle
no it doesn’t even make it to the nozzle tip. it just starts wrapping around in the alluminum parts therevabove the nozzle
Check the inside with a torch and see if there is any melted plastic from a filament change. Sometimes it can leave a string of filament after the change of the filament. Or if you have a silicone tube in there it might be sliding to far down
i totally threw my hands up with this thing. Isnt there a faster way for these printers to print.sure spikes the electric bill
ill put a pic of my machine up
I found the problem. Brobably. Before fix, 20x20x20 cube printed 19,98x19,94x17,34. After fix 19,97x19,95x19,89.
The fix was adjusting the z rods hight (have 2x direct z-drives) reference to The stepper motor they where abit out of line with each other. Making the z carriage warp and thus restricting the movement
I agree
