M322 T1 S1 R1 Movement Issues

Hi Denis,
 
Thank you for your X2V3 firmware, I like your addition of the mirror and normal duplication printing ability.
 
I was running the Marlin 1.1.0-RC8 with Dual_X_Carriages on M605 duplication printing. I have got it running on the following specs;
 
Control Board; Megatronics V2
Software Control: Repetier Host on Windows 10 Laptop, Also tried Printrun
 
T0 homes to the left to X0_MIN_POS, T1 homes to the right to X1_MAX_POS. T0 and T1 works when printing a single object separately.
 
However when I have the settings at M322 T1 S1 or M322 T1 S1 R1, T0 will move right onto the print bed, but T1 will also move right, away from the print bed slamming into the T1 endstop.
 
Would appreciate your input on this problem.  
Thanks,
Kwok

That is expected behavior. The "follow-me+mirror" mode is supposed to be turned on after the extruders are positioned on both sides of the printing bed. You can install the X2SW bundle and take a look at the start G-code for printing in mirror mode. Make sure to tell it to load the latest profiles from github. Here's the start G-code for slic3r profile:
Code:
;(This file is for ReprapX2V3 dual/duplicate printing from 2 extruders)
;(**** begin initilization commands ****)
 
; (homing and initial setup)
T0 ;(switch extruder)
G21 ;(set units to mm)
G90 ;(set positioning to absolute)
G28 ;(home all axis)
G91 ;(use relative moves)
G1 X1;(move X a bit off of the endstop)
G90 ;(back to absolute)
M331 S2;(remember that parking position)
T1 ;(switch extruder)
G28 X ;(home X axis for extruder 1)
G91 ;(use relative moves)
G1 X-1;(move X a bit off of the endstop)
G90 ;(back to absolute)
M331 S3;(remember that parking position)
T0 ;(switch extruder)
G1 Z0.0 F300 ;( adjust for platform going up due to heat)
G92 Z0.0 ;(set the z level of homing)
G1 Z10 F600 ;(move up a bit)
 
; (wait for tempearatures to set)
M109 A1 ;(wait for all extruders)
M190 ;(wait for bed)
 
; (prepare secondary extruder)
T1 ; (switch extruder)
G92 E0 ;(reset extruder to 0)
G1 F100 ;(set feed rate)
G1 E11.5 ;(feed some plastic)
G1 E5.0 F2700 ;(retract +0.5mm extra)
G92 E-6 ;(set filament position)
 
; (prepare primary extruder)
T0 ;(switch extruder)
G92 E0 ;(reset extruder to 0)
G1 F100 ;(set feed rate)
G1 E11.5 ;(feed some plastic)
G1 E5.0 F2700 ;(retract +0.5mm extra)
G92 E-6 ;(set filament position)
 
T1
G1 X200 F6000 ;(position extruder 1)
T0
G1 X0 F6000 ;(position extruder 0)
;M322 T1 S1 R1 ;(turn on follow mode w/ mirror for extruder 1)
M322 T1 S1 R1 F1 ;(turn on follow mode for extruder 1 w/ mirror, fan and move on to printing)
;M322 T1 S1 R1 H1 F1;(turn on follow mode for extruder 1 w/ mirror, fan, heater and move on to printing)

Hi Denis,
 
thank you for your prompt reply.
 
I am trying to stay away from slic3r, it seems that there are manifold issues when slicing the dual color Benchy STLs. Also prefer Repetier's GUI for the eventual shift to a RasPi with an LCD as the printer's controller.
 
Is there an alternate place to download the slic3r profiles, that way i can reference them while trying to set it up on Repetier? I tried your profile repository but there was no profiles in that link.
 
Side Qn, are u back mount or side mount? i am still waiting on getting time off to finish my full cave training, currently stuck on Apprentice. Cool videos btw

The profiles are on the printer-specific branches in the repo. The slic3r ones are here:
https://github.com/dob71/x2sw_profiles/tree/x2v3/Slic3r/printer
The Skeinforge start G-code is here:
https://github.com/dob71/x2sw_profiles/blob/x2v3/.skeinforge/alterations /mirror_start_x2v3.gcode
 
I'm doing the side mount.
