Mark, I actually do have some definite before and in progress pictures and right now the machine is moved to the spot in my shop where it will live for the duration. I have been scrubbing grease and chips off the damn thing since I got it here and underneath the crud it looks like a nice machine. I tried to post pictures on the thread before but only links will work I guess. I need to get them uploaded to pbotobucket or something to show them. I live in east Tennessee just south of Knoxville. Today I am supposed to be showing our home which is for sale so I have a bunch of lawn mowing and house cleaning to do before they arrive. I will get you guys some pictures soon tho. Right now it is not much to look at hehe. If the house finally sells all hell is going to break loose while we try to get my machines and all our stuff packed up for a move to Florida where I grew up.

Re: [Emc-users] Lathe conversion with Mesa 5i25 / 7i76
Yes, I've been looking for a decent CNC lathe for a while. There are a lot of really nice production type machines available cheap, however they weigh 12,000# and need 30-40HP worth of power for the spindle, hydraulic and coolant pump motors which is a bit of a pain for a home shop. I like full sized machines since I tend to work on larger projects, but I'm perpetually short on shop space (~1,200sf currently) and only have a 125A 240V 1ph feed to the shop. --Original Mail-- From: Gregg Eshelman g_ala...@yahoo.com To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Sent: Thu, 30 Oct 2014 00:46:13 -0600 Subject: Re: [Emc-users] Lathe conversion with Mesa 5i25 / 7i76 On 10/29/2014 10:42 AM, p...@wpnet.us wrote: It's a Harrison Trainer manual/CNC 280.

Re: [Emc-users] Lathe conversion with Mesa 5i25 / 7i76
I hear ya. My machine lathe and the Cincinnati arrow I retrofit both will be running on single phase power. The Cincinnati arrow already runs and makes parts but the toolchanger is not working yet with the control. Everything is wired up and working tho. The lathe retrofit is another story it will be needing some parts to get it running I'm thinking about$1500-2k or so and it will be done. Trying to scrape up some coin for that right now. Too bad you didn't contact me it's always nice to meet fellow linuxcnc guys and chat with them about machining and controls etc. I want to get to Florida where I grew up, I am not made for cold weather it seems I have begun to dread winter here.

Hey thats awesome... I just looked it up and it is actually very similar to my machine. I just bought a used HH Roberts Standard Modern 14x40 CNC lathe. Did your machine come with stepper motors?

Re: [Emc-users] Lathe conversion with Mesa 5i25 / 7i76
It has the original steppers and the much newer Microkinetics drivers. The spindle motor is ~1.5HP I believe, I have it on a 2HP Hitachi VFD. Did you mean your machine has DC brush type servos with resolvers (old)? If it has brushless AC servos (newer) it wouldn't have resolvers. In either case I'd stick with the original servos and drives if they are functional since they are probably well matched to the machine. If it has old resolvers I'd just replace those with some new inexpensive encoders. The MESA 5i25/7i77 servo card combo would probably work well, I have that card set waiting for a conversion on my much larger CNC mill after I'm done with the lathe. The mill has a Dynapath control currently that works fine, but has small memory so I just drip feed it serial from a PC currently. --Original Mail-- From: Pete Matos petefro...@gmail.com To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Sent: Wed, 29 Oct 2014 12:47:15 -0400 Subject: Re: [Emc-users] Lathe conversion with Mesa 5i25 / 7i76 Hey thats awesome...

Re: [Emc-users] Lathe conversion with Mesa 5i25 / 7i76
Yeah no actually they are indeed brushed DC servos with encoders. I might actually keep them but I am missing the Z motor so might as well get both new. The machine I bought gutted of the original control and motor. I did use the 5i25/7i77 combo on my Cincinatti Arrow 500 VMC retrofit. Excellent stuff. I will use the 5i25/7i77 combo I have as well for the new lathe. My machine came with a 7.5 HP motor apparently but it was an option base motor was 5hp. I am not sure which size motor I will get but it will probably depend on what kind of deal I can get on it. Gonna run a Hitachi WJ200 VFD like I did on the Cincinatti most likely. Cannot wait to see this monster make some swarf. Right now I am stripping and repainting a good bit of the sheetmetal as some jackhole mopped some cheap paint on it with a brush. Aah well if it was beautiful I probably would have paid a bunch more for it I guess LOL Good luck with your build.

Re: [Emc-users] Lathe conversion with Mesa 5i25 / 7i76
Andy, Like I said I would think about using the original motors if I actually had both of them. I only have the X motor here now so I wanted to have matched motors and drives for both axes. Still have a lot of cleaning and scrubbing and rewiring to do before I really have to worry about that so not in a huge hurry hell I may change my mind. Brushless DC motors with resolvers are not cheap on ebay tho. I could buy a complete motor and driver brand new for what I would pay for a used one like I have on the X. The machine has a heavy 1-1 belt drive on both axes so I could actually run about any motor I want on it even a big stepper would work actually but I want to try to go with an AC servo if possible.

Okay that is what I was thinking. Appreciate your advice. I am going to pop it on ebay and try to sell it for whatever I can get for it and use that towards the new motors and drives. I also have some other stuff here from both builds I don't need I will try to sell. Still have a lot of scrubbing and painting to do on it.

The MPG encoder are on the 7i76 and the 7i76 is on the 5i25 and this gives them names like hm2_5i25.0.7i76.0.0.enc0 To confuse things, there are wires from terminals on the 7i76 straight through to the 5i25 high-speed encoder(s), but that encoder counter is running in the 5i25 FPGA whereas the MPG encoders run in the 7i76 processor.

[Emc-users] Lathe conversion with Mesa 5i25 / 7i76
I'm back at work on my lathe conversion, reviewing what I have so far, cleaning up documentation, etc. I've run into an issue / question, hopefully I'm just missing something. I have my spindle encoder connected to the Mesa 7i76 TB3 encoder inputs, which seems to be ok (still have to test operation). I'm looking to connect my MPG encoder somewhere on the 7i76, and I though that could be done on regular inputs due to it's relatively low frequency operation. Looking in PNCConf I don't seem to see an option to put the MPG encoder elsewhere. Am I missing something? Is it supported but not in PNCConf?

Re: [Emc-users] Lathe conversion with Mesa 5i25 / 7i76
HAL supports a nearly infinite list of things. Configuration wizards by there very nature can only support a small subset of that. You can certainly load a software encoder counter and use it for the MPG. But if the Mesa card provides enough encoders (one per servo axis, one for the spindle, and one for the MPG), you might as well use a hardware encoder counter even though the speed is low. If you run out of hardware encoders, then use the software counter and a couple of GPIO pins.

The 7i76 only provides one encoder input since it's a stepper card not a servo card. Can you point me in the direction of some docs on loading a software encoder counter and configuring it for MPG use (one MPG, with axis and step select switches).

I believe you have two options. If the firmware is right, I believe there is a different 5i25/7i76 mode that has an MPG input. That MPG will be specific pins though (check the manual form Mesa) This is a nice option as there is a x1 mode just for MPGs. The other option is to load a software encoder counter and use any GPIO inputs to supply it (even a spare parport) I'm not sure if you would need a base thread or if the servo thread would be fast enough - but I would bet the servo thread is fast enough. Surely others can give you more specific answers. Chris M -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Configuration wizards by there very nature can only support a small subset of that. You can certainly load a software encoder counter and use it for the MPG. But if the Mesa card provides enough encoders (one per servo axis, one for the spindle, and one for the MPG), you might as well use a hardware encoder counter even though the speed is low. If you run out of hardware encoders, then use the software counter and a couple of GPIO pins.
