Laser Mod Delta Printer

Mekala

Hi
I added laser module to my delta printer. When I switch laser mod on duet wifi than pres home all G0/G1 insufficient axes homed error apears. When I try to move X Y or Z axis indivicaly with G1 H2 Y5 F6000 only one tower moving. How can I fix this ?

Board: Duet WiFi 1.02 or later (duetwifi102)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 2.02(RTOS) (2018-12-24b1)
Duet WiFi Server Version: 1.25

Code that I use for switch laser mod : (Using E1 Heat)
M307 H2 A-1 C-1 D-1 ; Disable Heater output on H2
M452 P2 R255 F200 ; Enable Laser mode, on output 2 (heater 2), with max intensity

@mekala Did it work properly before you added the module?
Does it work when you comment-out those two lines in your config file?

Here are some things people ask for to help you figure out your issue:

Post your config.g using the "Code" tag </>
Post your config-override.g
Post the results of running m98 p"config.g" from the CGODE console.

What does the printer do when you press the "Home all" button?

Also, your firmware is pretty old, so I think someone might suggest updating at least a revision or two.

Printer works normally when not in laser mode. I have macro file for switching to laser mode:

M307 H2 A-1 C-1 D-1 ; Disable Heater output on H2
M452 P2 R255 F200 ; Enable Laser mode, on output 2 (heater 2), with max intensity

When I run that macro I able to use laser module via M3 Snn command but ı cant home or move axis.
Normally when I pres home all button printer homes all axis without problem. When I switch laser mode than pres home all G0/G1 insufficient axes homed error apears.

Results from running m98 p"config.g":
HTTP is anabled on port 80
FTP is anabled on port 21
TELNET is disabled

firmware version 1.21

I'm not sure if M452 was supported in RRF1.21? The Wiki doesn't mention it.
Is there a reason, you don't update?

Mekala

@o_lampe
M452 mentioned here:
https://duet3d.dozuki.com/Wiki/Laser_PWM_control#Section_RepRapFirmware_2_x
Under RepRapFirmware 2.x:
M307 H3 A-1 C-1 D-1 ; Disable Heater output on H3
M452 P3 R255 F200 ; Enable Laser mode, on output 3 (heater 3), with max intensity being 255, and a PWM frequency of 200
I modified that for heater 2 laser works without problem

Very important! If you use M452 to put your machine into Laser mode and are running Firmware 2.02 or above,
you must replace all S parameters in G0/G1 commands in homing files etc. by H parameters. This is because S is now used to control laser power.

From: This link.

Maybe this is your issue?

@alankilian
Thanks its working now. is there a better way to do this ?
