Well in my particular case I am using the kflop w/ the snapamp (driver board) for my mill conversion which is using servos. I was able to close the loop in the kmotion software and tune it really quickly within the software... which was nice. Because the snapamp has plenty of I/O's to handle the mil...

Hey, I have a question for you guys. ;) Do any of you happen to know if the x and z datum sensors are used for limit switches as well as for homing? The reason I ask is that one of the LCB3's relays (labeled AUX in the wiring diagram) appears to be connected to the circuit for the datum sensors so I...

Thought I'd post an update on my upgrade progress. I switched over to a new USB-based controller board by https://www.dynomotion.com called "kflop" and I'll be working with the developer on solving the indexing issue for the existing spindle encoder. The kflop is mach compatible and has a built-in p...

I found out that the spindle encoder functions at 5v (input/output) so theoretically it could work w/ mach using the 1 ppr indexing channel. I am told that mach is unable to read more than 1 ppr and so it seems like an ideal match to me. If the 1 ppr indexing channel was originally setup to control ...

Thank you Magoo... that's great! I mostly just wanted to know what I was giving up by possibly letting go of the 60ppr channel with the upgrade. My most obvious concern was losing any threading capabilities so this is good news. So the 60ppr must also be used to indicate direction as well then I wou...

I'm looking into using the z channel on the spindle encoder to signal the one ppr that mach 3 requires for spindle control. Apparently mach 3 doesn't support more than 1 pulse so I won't be to make use of the 60 ppr signals generated by the A/B channels. So, I'm curious... does anyone know what the ...

Well, I can't speak w/ much experience regarding the g100 as I'm still pretty much in the initial stage of retrofitting the mill. I have successfully set it up and tuned the servos on the machine, but have only been able to cut some motor mounting brackets out of delrin so far because I still need t...

Thank you admin... those drawings are helping me figure out how to convert it over to mach control as you intuited. ;) I have an existing mach 3 setup with a Grex g100 driving servos for a benchtop mill and am currently only using 3 of the 6 available axis on the controller. I am considering purchas...

Thanks a ton Steve... that's exactly what I was looking for!

Does anyone happen to know if one exists or if one is available?
Either a schematic for the LCB3 controller board or a wiring diagram for the machine controller box itself (preferrably for a Mirac PC)?

Well, I was able to confirm that the serial port is functioning and tried launching from a winxp box through dosbox and that was unsuccessful as well. I have a feeling that it's the cable configuration that's causing it to fail. I had mixed replies in this thread about what the configuration is for ...

I am currently booting directly into DOS, although I have seperate installs of both win2k and winXP that I can boot into. I did do a quick test with dosbox on xp but received the same error. However, I didn't attempt to configure the port settings like the baud rate, etc... I will try to test the po...

Thank you for helping me with that... I really appreciate it! Well, I built a new machine cable based on the IBM compatible wiring diagram mentioned above (see image below) but am still getting the 128 error. Both ends of the cable are grounded and I wired everything up according to the diagram so I...

It looks like I'll have to order the parts needed to build the machine link cable so I'll have to hold off a few days b4 being able to move ahead on this. I have a question regarding the grounding of the shielded portion of the cable. According to the diag the shield connects to the "case" rather th...

Excellent... I will try this today and see how it goes.

Thank you for the help Martin!

I can't thank you enough for your help... that should be exactly what I'm needing. Does it matter that the wiring inside the control box doesn't match the cable diagram? I noticed that the color coding appears to be different than the diagram when compared to the wiring from inside the control box. ...

So, I have hit a wall with the rs232 cable configuration. I have tried a combination of 9pin and 25pin cable connections between the pc and controller board with no success. I have tried altering the mirac.go file along the way but am consistently getting the following error upon launching the softw...

Hey thanks for bringing that to my attention. 80% of 3000w = 2400w and the ID plate calls for an input of 240V @ 11A which equals 2640w. Do you think I would be safe with this? It's really close! I wasn't able to locate my old laptop so it looks like I'll have to buy one. It might be easier to get m...

That's exactly what I was looking for... thanks again! My next objective is to find a way to power the mirac pc. I only have 110/120v power here at my rental unit so my first thought is to use a voltage converter that will step-up to 220/240v. I found a converter that has a max capacity of 3kVA whic...

Thanks so much for the info, that is extremely helpful. I'm hunting around to see if I can find a manual for the software, do you happen to know if one exists? I imagine it's a pretty basic prog and I can likely figure it out on the fly but it would sure be a great help to have some form of referenc...
