Would you mind posting a link where you would have the indication of a product within this specification so that I can make the purchase.

I don't know where you are located, but the lead screw I am talking about would have specs like this one: https://spool3d.ca/lead-screw-8mm-1mm-pitch-1mm-lead/

A NEMA23 would be a good choice for the Duet2 because you can still find some good options at that size within the 2.4a limit of the Duet 2 drivers. Going up to NEMA32 would become problematic.

Given the size and lack of rigidity of the tronxy you may also want to consider automatic leveling using 3 lead screws and motors and a probe, (not 4, that's too many), in addition to reducing the lead screw lead angle.

@FABIO_F said in TRONXY X5ST-500 - covid19:

it shows an unevenness in one of the Z axes and automatically triggers the emergency stop.
In addition now it started to present some errors like:
Warning: motor phase A may be disconnected reported by driver (s) 4
Warning: motor phase B may be disconnected reported by driver (s) 4

It sounds like one of your Z motors isn't wired correctly. You can verify the motor phases with this: https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Identifying_the_stepper_motor_phases

The Duet 3 main board is available to pre-order now, see https://forum.duet3d.com/topic/11540/duet-3-mainboard-6hc-initial-production-run. But it's intended for more demanding applications than yours. You will need at least 7 stepper drivers (4Z, 1X, 1Y and 1 extruder), which is one more than the Duet 3 main board provides. So you will need the 3-stepper expansion board, which exists in Prototype 2 form but isn't in production yet.

OTOH a Duet WiFi or Duet Ethernet + DueX2 (or DueX5 to leave room for further expansion) would be more than adequate for you machine, assuming the 2.4A peak motor current available on the Duet 2 is sufficient for the motors you intend to use. Driving 4 Z motors needs no more CPU time than driving 1, because of the way the code is written.
