@dc42 I wanted to update you that I managed to do everything and the Multiple Motion System is very powerful, thank you very much everyone!

@T3P3Tony Thank you for your kind and valuable support. It's great!!!

@dc42 thank you so much for your answer.

Can I personalize DWC integrating different features like I said ?

Thanks, S

Hi all guys

I have a question and I didn't find any topics about that.
Is possible to use the Duet3D with a personalized software ?

I need of it for two reasons:
-Sometimes I'm forced to use my 6HC in a room without internet
-I should integrate in the software other external features, such as camera, UV lamp and others laboratories's stuff

Cheers, S

@dc42 thanks so much, I tried to follow this chapter but I had difficoultes to do that. There is an example that can be usefull?

@T3P3Tony you are right, I was not clear. The the UVW (syringe pumps) are not sinchronised with XYZ movements at the moment. But in the future a will need it.

Hello everyone,

I have built a 3D Bio-Printer and I use XYZ to move the end effector of the printer which extrudes bio-materials. At the same time, I need to control UVW in a different way and at the same time, I use UVW to control the syringe pump as you can see in the pictures, and I might want to control these pumps at the same time as the XYZ process. Is it possible to run a G-code to handle XYZ and UVW at the same time?

For example, I would like something similar.
I could run these two lines

G1 U200 F0.1
G1 U100 V100 F0.1

while these other lines are executed independently for XYZ

G1 X100 Y10 F600
G1 X-100 Y10 F600
.
.
.
G1 X100 Y10 F600
G1 X-100 Y10 F600

Could I do it?

@dc42
Does the firmware or the board have lower limits that do not allow stepper motors to be handled slowly?

@dc42 thanks for your support

I wrote this line solving partially the problem
M203 X3500.00 Y3500.00 Z3500.00 E3500.00:3500.00:3500.00 I0.01

then i tested the extruder and i got these results
G1 E1 F2 requires 30"
G1 E1 F1 requires 60"
G1 E1 F0.5 requires 100" instead of 120"
G1 E1 F0.25 requires 100" instead of 240"

I need to reduce more the feedrate reaching G1 E1 F0.025

Hello everybody,

i'm using a 6HC board and i can't control the feed rate of my extrution with F.
The speed of the stepper motor doesn't change using different feed-rate
I tried to use these commands without changes:
G1 E1 F0.1
G1 E1 F1
The maximum velocity is
M203 X1200.00 Y1200.00 Z1200.00 E1200.00
Any ideas ?
