s2m

S2M belts look like they have a 2mm pitch, just like GT2.

So 17 tooth pulley, 2mm pitch, 16x microstepping, and either 200 steps per rotation or 400 steps per rotation motors.

xy_steps_per_mm = (motor_steps_per_rev ∗ driver_microstep) / (belt_pitch ∗ pulley_number_of_teeth)

Gives you 188.2 steps per mm in X and Y if it's a 0.9 degree motor. Or 94.1 for a 1.8 degree motor.

No probe. That's fine.

The endstops look like makerbot style endstops, but there looks to be 4 wires going to them. It's really hard to see from the pictures. Maybe you could remove one of the endstops and take a good picture of the switch side with the wires. Also the wires at the other end that goes to the Duet. You'll need to identify which wire is which and how to hook it up to the Duet.

It looks like he might be using 18 tooth pulleys. How sure are you that yours are 17 tooth?

You may be able to copy and paste that config.g into your own file. It still won't help if the endstops aren't wired correctly.

twistedechos

i did modify the wiring with the end stops im sure i got it hooked up right but i can send a pic cus the duet is 3 wiers

twistedechos

twistedechos

it is 17 i counted again was hoping maybe my eyes messed up or something

So if you have 17 teeth, I would change his X and Y from 88.5 to 94.1. You can test if this is correct by moving an axis and measuring how much it actually moves.

If homing isn;t working correctly yuet, you can test movement by sending G92 X0 Y0 Z0 in the console to force the Duet to think it's homed. You can then carefully move the axis.

Have you tested his config yet?

The procedure for testing endstops should tell you if they are working.

twistedechos

end stops are working but the stepper will sit and bounce off of it? and when i did the G92 X0 Y0 Z0 it let me move it but then it stopped like it hit its max but it was in the center? and the 94.1 seems to be working well

twistedechos

i just found something else as well tool head number 2 fan seems to be getting really hot and not spinning i can spin it by blowing on it but i think it might be dead lol

twistedechos

im going to upload a better vid to youtube to show you what its doing now https://youtu.be/QgFb8Ch_efI

twistedechos

when we get this all figured out im going to put all the files on here for the next guy that needs help too

G92 X0 Y0 Z0

Ok so that tells it that it's at the lowest point of travel. so If your head is in the middle of the bed, it won't be able to go past 0 in one direction, adn it will think the other direction is longer than it is. It's only good for testing if the motors move in the right direction.

You'll need to actually home the printer now to get it to know where the real extents of travel are.

So can you confirm that +X moves it to the right, and Y+ moves it to the back? 0,0 should be located at the front left of the machine if you're looking at it.

You need to know that so you can tell the motors which way to move when trying to home.

You'll also need to know if the end stops are at the low (0) end of travel, or the high end (200+).

What happens if you try to Home X or Home Y? Are you using the files you posted above, or are you using the ones from that thingiverse link?

twistedechos

i think something is off x+ moves it to the back and y+ move it to the right let me check the wireing i wonder if i pulled up a bad diagram and it is the files from thingiverse also how do i find out what end the end stops are on? (sorry another edit) and when i try to click the home button it gives me the G28 G0/G1 error insufficient axes homed

twistedechos

@phaedrux again im being dumb i had x and y backwords

twistedechos

ok now they are moving the right direction but are now at the back right corner of the bed y end stop is at the low end i think do to pushing y+ and it moving away from endstop and x is at the high end do to pushing X+ and it moves to it

twistedechos

so it just needs calibrated right? and i got to adjust the size a little?

Phaedrux

@phaedrux said in duet 2 wifi ona ctc dual help plz:

M574 X1 Y1 Z0 S0

So you'll need to modify the endstop configuration in config.g to match the position of the endstops.

M574 X2 Y1 Z1 S0

That means Y is at the low end towards 0. X is at the high end towards 200+ and Z is at the low end towards 0. Is that correct?

Then you can compare your homing files using this section
https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_X_and_Y
For the low end, the homing move will have to move negative value. For the high end, it will move a positive value.

twistedechos

y is the only one on low end if anything going to + is high

twistedechos

sorry i was not correcting you it was a question i should have worded that better

what dose he mean buy this though?

Phaedrux

What is the config you are using now? (can you copy and paste it?)
What currently works, and what still doesn't work?
