this looks fine.

are you sure you have 4000 z steps and not 400?

this should only be

e0 is not required here because you are configuring the probe and its independent of the motorsM305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0
your bed is not configured correctly B4138 is not correct for an ender they use epocs 100k
-
I have a tronxy x5sa pro i wish i had an ender lol. Ill check to see if the bed setting is wrong but sofar its printed like that just fine so far. Well except for the lifting i get with large prints. The stock setting is exactly what i have for lead screws and motor. And when i tell it to move 10mm it moves 10 mm so id say it is the right setting. But ill check.

tronxy x5sa
according to marlins config
https://github.com/MarlinFirmware/Configurations/blob/import-2.0.x/config/examples/Tronxy/X5SA/Configuration.hthats also a epcos 100k
-
1 : 100k thermistor - best choice for EPCOS 100k (4.7k pullup)
#define TEMP_SENSOR_BED 1
-
-
ah ok never thought to look at marlin for the configs. ill set that up then and see how it works. and you where right about the 4000 i measured with my calipers and it was off. im sorry i doubted you on those.
-
Well so far im getting way to frustrated with 3. Im gonna stick with 2 for now.
-
what bit are you still struggling with?
-
I think its me but i cant seem to get 3 to work with my printer. It doesnt seem to like the e3d hotend or the bltouch or the bed. Ive being working on trying to get 3 to work for about 42 hours and cant seem to get off first base. so im gonna stick with what i know. The only thing is the dang z motors cant seem to stay in sync too well.

are all 3 motors the same model?
-
@Veti all of the motors are the exact same model. They are all tronxy SL42STH40-1684A-23 motors. 1.8* motors with belts or .8 pitch lead screws or a 7.3 hobb on the extruder motor. I think that most of my troubles are either the download that im getting from the configurator for the firmware update is not completely downloaded or the file coming from the server is not complete which is causing my issues with 3 not working 100% heck i cant even update my firmware to the latest 2.05 im stuck on 2.03 for some odd reason.

what is the error you are getting?
-
Just after i got your question veti i tried the update again and got this error its this one every time too. M997 S0
Error: M997: In-application programming binary "iap4e.bin" not found -

just upload this file to the duet. it contains all the required files. you dont even need to unpack it
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip -
@Veti thank you that worked like a charm.
-
ok so far i have both z's working in tandem on z1 and e0. I can do a true level and a mesh level. What else could i do to ensure the bed is as level as possible via the dual z setup on the board? i swear i saw an walkthrough last night that talked about probing at the lead screws and syncing them up some how.
-
now you need to find the lead screw position in x and y coordinates
in the example
the first is a position x-20 y0
the second is x220 y0
M671 X-20:220 Y0:0 S0.5 ; leadscrews at left (connected to Z) and right (connected to E1) of X axisthen you need to create the bed file and put in a position close to the leadscrews that you can probe on the bed
in this example we choose X20 Y0 for the first and X180 Y0 for the second

G30 P0 X20 Y0 Z-99999 ; probe near a leadscrew, half way along Y axis
G30 P1 X180 Y0 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors -
ok just so i get this right and not piss my self off. i measure with calipers from the lead screw to the probe? Or the nozzle? i havent had enough coffee or calm sanity from having to also teach my 2nd grader since schools are not "open" in our area yet.
-
from the nozzle.
the nozzle is the point of reference
-
ok this is what i got and filled in the areas. On the left side lead screw i have a measurement of 154.3mm from lead screw to nozzle. And on the right side i have a measurement of 89mm from lead screw to nozzle. and since i have the nozzle lined up on both lead screws i took those measurements and added on the right and subtracted on the left. If i did this wrong let me know.

now give it a try and run G32.
