I am configuring an IDEX printer with a Duet Wifi. I have the U axis connected and moving, now I am working on homing.
Currently I have the U axis endstop connected to the "E0 STOP" connector. Do I need to map this to the U axis somehow like I mapped the drives with the M584 command? If not, is it connected to the right spot?
The X and Y endstops are connected to their corresponding connnectors. I don't have a Z endstop so there is nothing connected in that spot.
Thanks!
Great! Thanks.
Here's the start of the printer. It is mainly assembled from laser cut 1/8 inch thick 5052 aluminum (surprisingly affordable if you find a good supplier) and Misumi 2020 extrusion.
It is still very early in the assembly phase, but I need to get a start at configuring the firmware to test the Z axis before I get too far along in assembly (made that mistake before and had to tear everything apart to solve binding).
I am commissioning a new cartesian IDEX printer powered by Duet WiFi and Duex5. It has:
1 X axis motor
1 U axis motor
2 Y axis motors (these will always make the same moves, but mirrored)
2 Z axis motors (these will always make the exact same moves)
2 Extruder motors
I would like to wire the motors as shown below:
So according to my understanding of drive mapping, the drives should be mapped as follows:
0: X axis
1: Y axis primary
2: Z axis primary
3: E0
4: E1
5: U axis
6: Y axis replica
7: Z axis replica
So finally my question is: Will the M584 command be written as below?:
[c]M584 X0 U5 Y1:6 Z2:7 E3:4[/c]
Great, thank you. I'll wire each motor to a separate driver and report back if there are any issues.
Thanks for your reply, I appreciate your input. The motors are Kysan 1124090 Nema 17 (https://ultimachine.com/products/kysan-1124090-nema-17-stepper-motor). 1.5 amp per phase, fairly standard 3D printer steppers.
The power supply is 24V.
My guess based on these specs is that wiring in series on one driver would be superior to wiring in parallel on one driver. But I'm not sure if using separate driver for each motor is better than wiring the 2 motors in series (since I will already have spare drivers).
Is there any benefit or issue with using a separate driver for each motor? Has anyone experienced superior results or risk of missed steps with either style of setup?
I am working on a new Cartesian IDEX printer design. Since it is rather large, I intend to use dual Y motors and dual Z motors.
In everyone's experience, is it preferable to wire dual motors like this to a single driver in series or to separate drivers that are mapped to receive identical commands with the M584 command?
Since I will already be using a Duex expansion board, It seems like it would be better to use separate drivers, but since I have never done it I am not sure. Any other pitfalls I should be aware of?
