Hi guys and gals. It's been a while since I have stopped in here. Life and all that, you know?

Anyhow, I recently bought a Plasmacam DHC2-- one of the early DHC2 tables. I did not get the PC...

Well, I finally have somewhat good news... I started shopping for a new drive since I figured we had pretty much exhausted all the possibilities with my current one. I was able to find a...

jfong,
I found that only version 2.16 of the VCI driver included support for the CANdy lite that I have. Possibly their earlier 1.xx drivers would have worked as well, but they have to be requested...

Well, I am about to give up on this amp. AMC got back with me and told me it didn't have to be enabled to talk to it via CAN. I spent a few hours with it a few days ago, and a few more today and...

...Crickets...

Anyone? I know the above is long, the TL;DR is below. I'm really stuck here. I don't think the drive has any issues, it looked brand new when I got it. AMC has not been very...

I built these a few years ago to get diffrential output from my single ended encoders. The IC was pretty cheap and required almost nothing other than itself to work. Here is a quote from my post...

Hi folks, I have some questions. I bought this DC202EE30A40NAC drive quite a while ago when I was gathering parts to convert my Bridgeport series 2 from steppers to servos. It has literally taken...

Hi folks! Long time no visit from myself. I had a setback on this project a year and a half ago, got a bit depressed about it, and due to lack of time and extra money I kind of let it fall to the...

It either had the ps input cap leak and burn or some nub hooked power up backwards. It is going to need pretty much a new board, there are two spots that are burned nearly through, otherwise I would...

The Servos are Nachi MSM302Q2V1 3Kw AC servos, I replaced the serial encoders with Renco incremental + hall tracks. Data sheet say's 200 Vac 18.6 A continuous, 80 A peak. I probably don't need the...

I'd honestly rather keep the price down and wait vs. spend a lot and get it right now.

Feedback is incremental encoder + halls, but it is not strictly necessary that the drive does the...

Thanks, the link is bad, but I did find it on ebay. The 30A max drives would probably work for this axis, but those are only 80V amps, My supply is 330Vdc. Anyhow, this is what I have been finding...

I have been working on my servo conversion for about 6 months now off and on, I finished my power supply a few weeks ago, and was going to start bench testing my amps and servos and the first of my 3...

I got a little more done... The case is all buttoned back up, there is now a barrier strip on the back of the case that has input for the control voltage, 110 in for the small ps, I shouldn't need...

Well, I got a little bit more accomplished today before life intervened and forced me to stop early. Basically all I got to was making an aluminum mounting panel for the fan, rigging up a filter,...

Hey guys, sorry for the long delay on updates. It has been a rough summer, I have been having trouble with my diabetes, had a piece of crap car I had to work on every free moment and all the other...

Good deal, one thing I forgot to mention, was the lower the quill is in the bore when you start, the easier it is going to be to get those top screws. My machine was not in running condition, so I...

This is from memory, so it may not be 100% correct, but, I got mine apart before I had the manuals for the machine, and it is not a bad job. If something I say doesn't make sense, spend some time...

Did you ever get this pulled? I've done it and it's not to bad a job, I'll post up instructions later when I can do it from a real computer and not my phone.

Later,
Jason

I finally fixed my bijur pump on my BP S2 a few months ago. Mine the motor turned, and the gears inside would slowly rotate, when I initially rebuilt the machine I thought it was working, but it...

I haven't been working on this the last few months, I have gotten sidetracked with summer and family. I missed the comments on my supply, but I did a lot of research before I started, and Al is...

Well, I have it up and working how I want it. The mains contactor energizes at ~215Vdc. The magic number for the relay coil resistance ended up being ~21.5K.

I needed a power resistor for the...

Update for today: I got the supply working. The voltage sensing relay resistance still needs some fine tuning, it pulled in at 120Vdc w/ a 10K coil resistance. This is about 120V lower than I...

I think I see what I did wrong! Coil current is ~27ma, when I read through the data sheet, I used the figures for a different relay, same model, different coil. I'll go back through it and see if I...

I gave the supply a test run on the bench today. The good news is, the AC caps work great to limit inrush, the buss takes approximately 10 seconds to come up in voltage. The bad news is, the relay...

Well, I made some progress today. I got a long ways toward building a supply on my bench for testing the supply design, and if that goes well, then testing the servo amps and beginning tuning. All...

Here is a schematic of the plan for the PS. A guy on the HSM board suggested I use AC motor run caps instead of power resistors for in rush current limiting, so I designed this way. I *think* this...

Finally, I am off work for a while and am back at this. I am starting on the DC PS, that's the last thing on the list before setting up everything on the bench and beginning the rough tuning...

About 2 years ago I bought a Series 2 Boss 6 machine made in 1982 for $500. The machine was in about the same shape as what you are looking at there. The S2 is quite a bit more rigid than the S1. ...

I made a bit more progress over the past few days. Not feeling so well, we had a cold snap here and I of course started to come down w/ a spring cold...

I got the shaft adapters all finished,...
