Troubleshooting non responsive machine- Mach3/Syil x4

[JAZZCNC]

Ok just read thru this thread and the fact it was working before moving and no changes made other than new PC then logic dictates the fault is with the PC and the PP port or PP driver. It's certainly the first link in chain that needs to eliminated.
Suggest you go back to basics and start at beginning.
Also some PC's use parallel port cards that are not compatible or work on different address to what's set in mach. Some also only output 3.3v and your BOB could require 5v.

So firstly are you using the PP cable which ran the machine before.? If you have replaced the pp cable it must be a straight thru cable (null modem), pp printer cables are often not and cross over pins so cannot be used.

Next I'd delete and reinstall mach3 and the PP driver with new download using latest driver to elimimate any chance of software corruption. Write down the settings you know worked before deleting.
Re-enter settings in new mach install, don't use the old xml as it could be corrupted.

After this then you can move onto the electrical side. To be honest if not PP Issue then I'd just buy a cheap £5 BOB. This instantly tells you if old one is the issue.

As I read it, the PC replacement was after the machine was moved and failed. There's a chance something was damaged, disconnected or shorted during the move. Right now with the images I'm not convinced this isn't a FrankenSyil machine.

OP: Are you the first owner of this?

Not, I bought it second hand.

Also I just read the thread that was linked above and seems it’s not a simple task to replace the bob, they don’t make the one I have anymore ?

Sorry, I know more questions than answers. That board that presents the connector similar to the ESTOP connector - there's three wires - L, N and FG wired up. Is there ANYTHING else wired to that board?

This is really looking like a FrankenSyil machine. That board ("Main Board") is the primary supplies for the rest of the "normal" X4 as well as the 3-phase controller for the brushless spindle motor. None of that appears to be wired. If that's the case, it's not necessarily a bad thing but might help us understand how much of the standard Syil configuration can be ignored. Right now I'm half convinced you can lose that board.

The bob is powered from it - the red wire coming from it goes to the ‘com’ pin on bob.

I recall the guy I bought it from saying he installed a different spindle in it if that’s useful info

I got the new pc as I thought it mite have been a pc issue - same problem with the original pc.

Have reinstalled Mach3 with driver - I’ll try again + entering settings not XML file.

Also just tried the original cable and no change.

I’ll order a bob now
