Good Morning folks. Im Rick. New member as of, well, 1 hr ago!!!


 I  just picked up a Compact5 cnc from the local high school. I got it very very cheap!!! It didn't have the key, but I bought on off Ebay. Now the problem is, the wires going to the Z axis were pulled out of their respective location. There are 6 wires that need to be put back. Can someone tell me which location the individual wires go? Thank You in advance.

Re: Compact 5 parts

Hi Brian,

Not sure I need any parts but it is great that you are offering them to people who can use them.  

I do have a question though.

What motor controller did you use for the spindle motor?  I am assuming that you have a 90 vDC and you did not use the old one. 

Also, did you hook up a spindle encoder?  If so can you provide details?

Thanks,

Gary

Compact 5 parts

brian@...
 

We just finished retrofitting a couple of Compact 5 lathes, and have a bunch of parts left over.  There are 2 complete (as far as I know) control panels, and 1 set of stepper motors.  One lathe was working fine, so I assume all the electronics were good.  The other lathe was partially working; the spindle speed control was good, but the stepper motors were erratic.  Both consoles are pretty beat up on the faces

I'm not sure what, if anything, this stuff is worth, but I will look at all offers.  I'm in Canada, so be aware shipping might be high.

A few questions...

Jeremy Gritz
 

Hi all. I recently (and by recently I mean a few months back, but the shop's been a mess and I haven't had the time) acquired a C5 CNC, fully working with the original control cabinet intact. I'm of the mindset to not fix what isn't broken, and I think it's a cute little lathe as is, so as of yet I don't think I'll be modifying it to a more recent controller. Which brings me to my questions.


1) What CAM does everyone use? I've got the trial of Dolphin PartMaster and am having fairly good results so far, though I've only done a few parts and have yet to actually cut any. I've tried CamBam but it doesn't have an EMCO post built in as of yet. I'm trying to get it to import directly into MFI as my shop computer isnt my CAM computer.


2) I've used the Dolphin Post Editor to formulate a post-processor that looks really close to MFI's format, though it's still not loading into the editor. What exactly is the format for MFI to be able to read it? I know it has to be a .nc or .cnc, but what charcter formatting does it look for?


3) Does anyone have any recommendations as to good tooling to use on this little lathe? I've got some indexible carbide tools off of Amazon that worked well on my 10" manual, and some other tools from Harbor Freight that are questionable (they were cheap and I got them on a whim just to try).


Thanks,

Jeremy

Re: QCTP - Emco CNC Quick toolpost vs AXA type?

uli schnelzer
 

I use it and it works ok. But its incredible slow compared with the tool turret. At the moment I need 5 tools for the part and that needs 2 minutes to change all the tools. But I can't change it with a turret because I need 4 outside tools and only 1 drill. Eventually the part-off tool can be assembled on the back of the X-slide, but for that I have to change many things on the machine. And if sometimes a part needs more than 3 tools I must dismount the turret. At the moment I haven't discovered any holes or other things to reach a repeatabel position of the turret or QCTP.

Maybe I try to change the tools with a small (Scara) robot and a pneumatik or hydraulic cylindre to open the clamp.

Art!!  To expand on what krlynn53 mentioned.  I was able to create a hal file in linuxcnc that creates the required strobe signal needed.  So no circuit board hack needed.  Also the emcos come with a 2 channel encoder (100line + index) which works very well as is.

Thanks, Sam. I'll open up one of the others and see what I can figure out. I've never been very comfortable messing around on that side of the machines. 

Re: Un-retrofitting an Emco Compact 5 PC?

Or...

If they did jump all of the pins on the octal latch - you could set the switches on the interface board to match your lathes running linuxcnc.  they should 'just work' then..  :)

If you set the switches on the interface board so it is the same as the ones running linuxcnc - it should 'just work'  (assuming they jumped all the pins on the octal latch..)

Re: Un-retrofitting an Emco Compact 5 PC?

samcoinc2001
 

I think you could use stepconf to setup a lathe.

These are probably the pins for the mach conversion

x step pin 2
x dir pin 3
z step pin 4
z dir pin 5
index pin 12
estop pin 11
100 ppr sensor pin 10
74ls374 enable pin 14

Re: Un-retrofitting an Emco Compact 5 PC?

Thanks VERY much for the reply. I have several Compact 5 PCs. To the best of my my knowledge, none of them was modified in any way to run with LinuxCNC. Three of them came from Sam Sokilic, who was also the source of the LinuxCNC ini and config files I use to control four EC5 PCs. I'm certain Sam told me an advantage of using LinuxCNC rather than Mach3 was that the former does not require any circuit-board modification. 

FWIW, although I've disassembled the working side of one of my lathes down to the last screw (excepting the motor and bearing assemblies), I'm virtually clueless on the controller side (i.e., inside the red box). So you can't insult my intelligence.

Thanks again.

I should mention, you might want to add an encoder to the spindle if using linux, it has great encoder based threading. Other than that the m3 mods should work fine
for you.  ( I wrote those mods originally, its all just step/direction control..)

Typically, the Mach3 control mod’s for a Emco are identical to the Linux mods. My Emco is Mach3 converted, but I could plug it directly into a linux system as well.
Sounds to me like you simply need to reconfigure your pinouts and should be fine.

I picked up a very nice Emco Compact 5 PC that had been retrofitted to run with Mach3. It's a late version that appears barely to have been used. I know it was executing the chess-piece program before I bought it, but without a key inserted, which I failed to notice in a video the seller provided.


The machine powers on when it's plugged in. The spindle motor is properly controlled by its switch. I use LinuxCNC and understood that I was taking a chance that the retrofit might have rendered the machine unsuitable for control by LinuxCNC, at least with the configuration I use for my un-retrofitted machines, and possibly altogether.


When I connected the parallel cable and tested the steppers using manual controls, what resulted was as follows:


- Giving an X+ command produced a combination of X- and Z+ movement.

- Giving an X- command produced a combination of X+ and Z- movement.

- Giving a Z command produced no movement.

 

Questions:

 

1. Are all of these observations predicable given the the modifications involved in retrofitting a Compact 5 PC for use with Mach3?

 

2. Can anyone advise/instruct me on (preferably) reversing the modifications and/or (less preferably) revising the configuration file for an un-retrofitted Compact 5 PC to allow it to be controlled by LinuxCNC?

 

Thanks in advance for any help.

PS i used Easus partition manager which is free and brilliant to partition the drive..there are excellent videos of how to use it on youtube :)

ive yet to export a file but im hoping that wont be a problem and im sure it wont be insurmountable if there is one.

Hi Alan,

Welcome aboard!

It’s on the website - https://groups.yahoo.com/neo/groups/Emco_cnc_users/files/Emco%20compact%20%205%20cnc%20lathe/

Under “Compact 5 Cnc Maint Manual.zip” and is actually in the last file - “181-233 maint. manual.pdf”

It is very heavy but can just be lifted by one person but is very awkward. The F1 CNC mill portability is another issue altogether!

I have not had cause to take mine to pieces but partial disassembly to reduce weight is not something I personally would advise because it is not a quick task. However, the easiest would be to take the lathe bed off the base/cabinet, but having to remove the motors from the lathe first otherwise all the wiring would have to be disconnected from the electronics. The lathe is not heavy in its own right. The casing is and would still be awkward to handle even without the lathe on it.

Good luck with your bidding.

John

Newcomer to the group .. hello all!

Short story is that there is a Compact5 CNC for auction locally, which could go for a lot of money (in which case I walk away) or could go decently cheap, in which case it's MINE!  

I'm now studying the manuals I've found online and in the Files section, but one thing I haven't found yet is an exploded parts diagram.

The use for such a manual once home is obvious; take everything apart, clean it and hope it all goes back together again.

But the real use will be to help getting it home.  I'll likely have to move the machine entirely by myself, which will certainly require some disassembly.

So, could anyone point me to either a parts manual OR some disassembly tips?

Thanks in advance.

Re: Start problem

KR Lynn
 

Thanks. Just saw this reply. There was another one that disappeared. I think it identified the mechanism as a thermal overload reset button. In any case, it was blocking operation in the absence of any appreciable heat. It seems to be functioning properly now. We'll see whether that continues. 

I'm guessing I'll have to do a capacitor replacement one of these days.

Re: Compact 5 PC LinuxCNC Config file

I also just uploaded the file, although I'd guess that's already been done. I didn't notice it, though.
