Hello to all,
I am rebuilding my old Geeetech G2s pro delta printer.
Basically I have build an outer frame around the original to increase stability and changed everything else besides the stepper motors.
As mainboard i use a MKS robin nano v3.1 with for now marlin 2.0.9.2 running on it. (thanks to great help of Dust)
Now i am stuck going to the next part, calibrations
At first I tried to move the hotends around using the marlin LGVL_ui. "tool / move / z- (10mm).
If I do so the steppers do move it down.. but very twitchy and loud (using tmc 2226 with stealth chop active) but there is movement is observed.
After a few seconds after the first filling that first assignment (very very far from smooth)
It gives the error..: driver error, printer halted, please reset and then it turns off (probably because i have MKS PWC installed).
Additionally I should also say that I am not using the standard ball bearing lineair bearings but those plastic once (NOT for aliexpress),
to decrease overall load on the stepper motors.
so after that, I thought it would be a better option to stopplaying and connect to the board via cura.
But, since my printer isn't in the cura list. I had to choose custom FFFF, but this seems to be a cartesian style printer and mine is a delta and no clear options to change that. (only square and oval print beds)
So I was wondering where to go from there.
Should I kind create a .json style setup for my printer? or are there other better ways?
Additionally, I don't know exactly what stepper motors the original g2s pro uses.
Today I recieved a msg from Geeetech though saying:
we do not have specifications: only know the model is like 42SHD0034-20B
So now I am also wondering.. since I changed my setup from 12v to 24v
with 220v for the bed heater. I set my Vref (tmc 2226) to 850mV as they should be 1.5A capable steppers.
Does the 24V on the system have any influence on the stepper motors? should I upgrade these?
the TMC2226 have a Voltage Range 4.75... 29V DC, so 24V is oke.
the board is also 12v and 24V capable.
I set the board as 24V in marlin.
Kind greats
Matthieu
