Help on custom Delta printer buildposted in 3D Printing General Chat
Hello everyone!
I am building a custom delta 3d printer and I could use some help on calculating the rod lengths.
I made a simulation of the geometry in the following link
http://danalspub.com/DKcalc/?he=1000&ve=2000&dr=900&lr=1550
The vertical extrusions will be 2000mm as I already have them.
The horizontal extrusions at 1000mm give me a printable radius of 316mm which I am happy with.
Is the ratio of the horizontal extrusions and rod lengths in the simulation correct or is there is a better solution?
Thanks in advance for any help!

RE: Mixing Extruder with Internal and External Driverposted in General Discussion
@deckingman What exactly do you mean by (quote) " The problem is that the motor connected to the external driver doesn't behave properly". ?
I mean that when i try to change the microstepping through :
OLD : "M350 X16 Y16 Z16 E16:16 I1"
NEW : "M350 X16 Y16 Z16 E16:2 I1"or steps per mm through :
OLD : M92 X80.00 Y80.00 Z80.00 E292.24:141.73
NEW : M92 X80.00 Y80.00 Z80.00 E292.24:500the motor at E1 behaves in the same way that it used to as if the changes didn't take any effect.
Setting E292.24:141.73 or E292.24:500 makes no difference at all at the distance the motor travels for a movement of 100mm

Mixing Extruder with Internal and External Driverposted in General Discussion
Hello everybody!
I spent most of my day today trying to configure Duet 2 wifi for a mixing extruder setup. I want to use one internal driver for E0 and one external driver through the CONN_LCD pins for E1.
I followed the documentation for the drive mapping etc and I managed to get both of the motors moving.
The problem is that the motor connected to the external driver doesn't behave properly.
After trying every combination in the config I could imagine and reading any post I could find on the forums I read that it is not possible to combine internal and external drivers on the same axis. Is this true?
If thats the case I guess I should drive both extruder motors through the CONN_LCD (drivers 9 and 10)
