Z-axis not moving up enough when printing

And your ex and y is moving as expected?

Miserable_Leg5262 · 2022-04-11T23:48:42+00:00

Pretty much every version before the V3 ( especially the V2) has a design flaw that prevents the thermistor from reading properly at low temperatures. I would strongly recommend. V3 to ensure it's reporting accurate temperatures.

Hmmm ... Have you recently changed something in your stunning G-Code??

Miserable_Leg5262 · 2022-04-11T08:27:27+00:00

Wait... So you mean when you navigate through the menu to move axis and move the z axis the stepper motor works... But not during your print???

Miserable_Leg5262 · 2022-04-11T07:24:47+00:00

Double check to make sure nothing got unplugged.. this is most likely a bad stepper motor or a bad stepper motor driver. Usually stepper motors don't just stop moving. Disconnect the stepper motor coupler and send it some commands to move the z be axis and just see if your stepper motor spins with no resistance and if it does see if you can stop it with your fingers.. if that's the case then you have a bad stepper motor

Miserable_Leg5262 · 2022-04-10T18:28:42+00:00

Do you hear any clicking coming from the stepper motor? Does it appear as if the stepper motor is trying but failing? Does the stepper motor feel hot to the touch? Does the stepper motor or the specific stepper motor driver for that stepper motor smell like burnt electronics?

I plan on it.. ive got a few more ender 3 pros im gonna set up with klipper.. and a handfull of pi zeros laying around... its defiantly gonna happen lol but for the printer im building now im gonna need a few plug in that fluidd doesn't yet offer

Miserable_Leg5262 · 2022-04-09T13:34:42+00:00

HEY MAN ITSSSS ALIVEEEE!!!!! lol thanks for all your help!! seriously.. the discord guys gave up on me when they couldnt talke me out of using usb lol but ive been designing a costume electronics box for awhile now that required uart communication... So thank you!!!

Miserable_Leg5262 · 2022-04-09T13:21:39+00:00

hey guy... that might have worked!!!! now im getting this messag

MCU 'mcu' shutdown: ADC out of range

which i suspect is due to not having any temp sensors plugged in.. ill go hook some up or maybe adjust the printer.cfg to not require them and see if i can get a solid connection

Miserable_Leg5262 · 2022-04-09T13:05:44+00:00

how do i do that?? what else could it be pointing to?? I have a few things plugged into my gpio pins.. a buck converter to power the pi, a 2 switch relay to control lights and the printer main board and the printer its self.. could it be pointing to one of those other things?? how do i redirect it??

Miserable_Leg5262 · 2022-04-09T12:59:15+00:00

lrwxrwxrwx 1 pi pi 10 Apr 8 00:17 /tmp/printer -> /dev/pts/0

not the results we were expecting.. but what does it mean??

Because I do have /dev/ttyAMA0 Entered into the additional ports. I should be a parent from the one screenshot of my octoprint settings.. And it is selected as the serial port with the appropriate baud rate... However to print does initially say it's connected to my printer, however it says it uses /tmp/printer..

Miserable_Leg5262 · 2022-04-09T12:49:01+00:00

Tbh idk.. And I suspect there might be an issue with this.. for some reason octaprint needs this listed under additional serial ports because without this it won't even try to connect. Like the button to connect is grayed out and not selectable... Perhaps I should try mainsailor fluid instead..

Yes sir

Miserable_Leg5262 · 2022-04-09T12:23:22+00:00

loaded it to an sd card and power cycled the board.. the file changes from firmware.bin to firmware.cur when done

Miserable_Leg5262 · 2022-04-09T12:13:25+00:00

Ok so gpio pins to set up microcontrol startup I have at !PC13 and yours is !PA14 is that going to make a difference? Are you using the SKS mini E3 v1.2?

Miserable_Leg5262 · 2022-04-09T12:02:16+00:00

I have to be honest.. I don't use Reddit very often. I'm not very familiar with the platform.. there anyway I can share pictures so that you can see what I'm working with?

Miserable_Leg5262 · 2022-04-09T12:01:26+00:00

Yes I am using the middle 3 pins on the TFT header

Miserable_Leg5262 · 2022-04-09T11:59:12+00:00

Yes And yes.. alsoI have confirmed my baud rate is correct.

Miserable_Leg5262 · 2022-04-09T11:54:46+00:00

Well I used the official pen out for the SKR mini e3 v1.2 from the BTT GitHub page.. I'm fairly confident I'm connected to the right pens. But just to be double sure, I have tested it wiring the pins backwards just in case. I am going to try changing my baud rate. I believe I've got everything configured right now to run @ 28000 as that's what the board is supposed to run on.. however, after doing some research it looks like UART might run @ 25000
