Migrating buildlog laser from pport to 5i25 was created by sliptonic
I have a retrofit 40W laser that uses
Bart Dring's buildlog breakout board
for controlling the laser and step/direction. I've been using this with software stepping on a parallel port for a while but I want to move it to a 5i25 without a daughter board. The pin assignment on the board roughly matches the prob_rfx2 configuration but not exactly. From the manual:
in # Function (goes to)
1 Output 1 (Relay Driver 1)
2 X Step
3 X Dir
4 Y Step
5 Y Dir
6 Z Step
7 Z Dir
8 Output 8 (Relay Driver 2)
9
10 X Limit Switch Input (J3-6)
11 Y Limit Switch Input (J3-8)
12 Z Limit Switch Input (J3-1)
13 Input 13 (J3-2)
14 PWM 14
15 PWM 15
16 Motor Enable Output
17 Laser On
18-25 Ground
Will I need a custom bit file for this?
Also, just experimenting, I tried to get pncconf to see the other config XML files downloaded from mesa's site. Based on posts in this forum, I copied those to /lib/firmware/hm2/5i25/ and restarted pncconf but they were not seen. Has the correct location for these changed?

no.
check the permissions of the folder and file.

The only thing thats looks incompatible with probrfx2 is the two PWMs
Are these 2 independent PWM outputs?

@cmorley: All the files are owned by root with no one else having permission. What should it be?
@PCW: It's looking for a PWM source to control the laser power. It's select-able with a jumper for either pin 14 or 15.
I guess I'm not clear on how to use pncconf to set this up. The I/O connector 3 tab has me confused and when I try to launch the test panel, it appears for a second then disappears with this error:

Looks like just changing one pin definition (removing the PWM direction on DB25 pin16)
will make the probrfx2 config fully compatible

I'm sorry. I don't understand how to do that. pncconf is making more sense, but I still don't understand the mapping of the 'num' columns to the I/O and pins from the .pin file.

yea dont use the test panel in pncconf , and you be ok
make your configuration as near as you can then i'd edit it by hand
or shout if it's a problem

To be able to use pin DB25 pin 16 as a output bit and use the PWM pin on DB25 pin 14,
a special modified bitfile would be needed (since the PWM part of the driver will claim pin 16 as a PWM direction pin)

O.k. Is that within the scope of a strong-back/weak-minded (but willing) amateur or is it something I can get from you?

Has a simplified prob_rxf2 config with the PWM direction pin removed so should work with your BOB
