Might need to use Dropbox or YouTube

twistedechos

i wonder if anyone has the original gcode files for the ctc my old board fried if i could get those i should just be able to upload them to the board right?

twistedechos

also i went thought the stuff you sent and it didnt do anything i think i need to reuplaod the files on it but i dont think i did the maserments right on the reprap config i think that might be the problem how do i find them all i can find on google is the bed size

twistedechos

i feel so dumb i think i found the problem i did not put the files under sys it is under another folder ill let you know what i find out

twistedechos

ok that fixed it oi lol but now the problem is i dont think i have the right measurements or the home set properly i went thought the reprap config again and i dont know the specs for the printer nor understand what to do with them

twistedechos

found another problem haha sorry to be spamming but i had it as a corexy (what i thought it was) its a cartesian

twistedechos

next problem i have no idea what im doing lol i got it to do stuff but its doing crazy stuff its like id dont know where to stop and anytime i home the axis it acts like it just adds the steps to where it already is i dont want to burn anything up would anyone be able to walk me though the https://configurator.reprapfirmware.org/Start

Ok, it sounds like you made some progress. Before you can get things working, you're going to have to figure out some details about the printer. The link you included above shows the build volume, so we have that part. We know it's cartesian. It seems to be dual extruder. it has a heated bed.

What we still need to know:

What kind of thermistor does the hotend heaters and bed heater have? If you have any documentation, or support forum for the printer that might help. Some googling might turn it up. That would help getting the temperatures right without having to do too much guess work.

We need to know what kind of end stops you have and where they are located. Even if you can take a picture of them inside the printer and how they are wired.

Does it have a Z probe?

Steps per mm for each axis. You might be able to find this googling, or looking at the setup for the stock firmware. Worse comes to worse it can be calculated if you know the model of the motor (usually a sticker on them), the tooth spacing of the belts, and the number of teeth on the pulleys. If that's too hard to get, you can start with a safe value and test how much it actually moves when you tell it to move 10mm and figure it out from there.

I think you'll also benefit from doing a lot of reading up on the firmware and how things work: https://duet3d.dozuki.com/

Here's an article on adapting an existing printer for the Duet. https://duet3d.dozuki.com/Wiki/Going_from_Marlin_on_Arduino_to_RepRapFirmware_on_Duet

thats the bad part i can not find any info on this printer and it dont have a z probe unless that is the z endstop non of the endstops seem to be working they light up when pressed but the stepper will try to keep moving ill get some pix for you guys in a sec

twistedechos

z end stop

twistedechos

y end stop

twistedechos

x end stop

twistedechos

belt is s2m and 17 tooth pullys z rod is the 8mm rod and a k type thermistor it is a 24v system if that helps with anything the bed thermistor is built into the bed

twistedechos

i did find this though https://www.thingiverse.com/thing:2475257/ im not sure what he means in the files though

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

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.

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
