Hey kitten just google deep hole gun drill this is how they made gun barrels. I once drilled two 5/8" parallel holes thru 36" 4140 and only had .010 run out.

If the price is right go for it. You sound like you can do the job.I took a Boss 5? and retrofitted it with new nema 40 stepper motors, gutted the controls, wound a new transformer, VFD for the...
Go back and reload an older XML file from before the trouble started seems to work for me. Glitches happen and when all else fails you can always reinstall everything.

Hay I'm at the age that I am lucky to be able to answer the telephone the first button push. I think I have an old Kodak laying around somewhere. I do have a small camera but posting the pictures may...
Was told it was a boss 5 when I bought it. I made no changes to it other that replace the motors and controls. has a serial number stamped on the ways of "CNC 4208" will this tell us more about it?...
I did the motor swap to nema 40's had to make shaft adapters. Built a 70v power supply and using gecko G201x drives. My Boss 5 has 2 to 1 reduction on the lead screws. I kept the travel dials they...
google vfd motor harmonics
I did a Denford Micro Turn a few years back. Running Mach3 I had to hack all the pin outs on the Denford board. I found the pin out somewhere on the net. May not be the same machine thou. It ran OK...
AHA The old missing steps trick. I didn't think about that. I have a Bridgeport Boss 5 with NEMA 35 motors and don't have a missed step problem. Unless I try to move to fast.
Where is the top of the material? Look at the end of the G code file. I always edit my programs as I get several extra lines that my post processor adds in, especially a G28. The G28 will take it to...
In the machine shop I worked at we used WD for rust prevention. But what I found out is, if you store your tools on the open back shelf you will accumulate dust on the fresh coating of WD then the WD...

Go to Newfangled Solution's Mach's forum there is where to ask about anything Mach3.

Yea been awhile since I have needed help.
You can run at 24V but is better at higher voltage. You wire directly to the 540's terminal board. The 540 can control the VFD, check the documentation it is good and the folks at Gecko Drive are...
Cause is loss of steps on the Z. Lower the velocity setting. Using stepper motors the controller tells them to move but being an open loop system it has no way of knowing where it is. If you have...
When I did Aerospace parts for NASA We had to leave the tool swirls on. We could buff a little with scothbrite brown but no removal of the tool marks. Wasn't given an answer as to why. The first...
I have an parallel port running my machine's. A Denford Microturn lathe, Bridgeport Boss 5 millI plus the one I built from scratch. I know the newer stuff as migrated to USB built my first mill 12...
Welcome to the fun of CNC Unfortunately Mach3 will not work with a USB controller. I tried and had no luck awhile back using a USB DB25 parallel port adapter. Go to machsupport.com that is where you...
That is not a milling machine. It's not ridged enough. Carbide cutters will chip and brake with the vibrations that are generated. You might try HSS cutters but rigidity will still be a problem....
I converted an older Denford Micro turn to Mach3. Probably different animals now though. Post a picture of the control panel. I had to hack the pin outs on the board to adapt to the BOB that I...
I use Mach 3 it has a provision for adding tabs to a profile. No holes needed except in the waste stock.
Sneak the wife's cloths iron out to the shop and apply heat to the parts. It may loosen the adhesive enough I would think. I use double sided foam tape to hold parts down when the part has no holes....
diecutter has the right solution. Add the screws then the parts can be cut without being thrown about and no end of cut burrs. I do this all the time myself.
Thanks Dave glad your up and running. I'll try not to hurt my arm patting myself on the back.

I too struggled getting my CNC machines up and running at first. Not understanding how it all works is very frustrating to say the least. This is just part of the fun of DIY CNCing. Makes one smile...
If you copy and paste your current "Machturn.xml" into a new installation you should have no problem. It holds all your current calibration data. Machturn.xml is what mine looks like though I don't...
That is why you save the latest XML file it will be named whatever the profile name is. Mine is "Bossman.XML" yous will be different. Could be Mach3.XML if it has not been renamed. Look for that....
Save the complete Mach3 file folder to a zip drive. Get the latest Mach3 from there website "your latest XML file and Lic files must be saved" Now delete Mach3 from the computer. Do a search to make...
Another problem when I converted my Bridgeport Boss 5 to CNC I used the old wiring. What I experienced was crosstalk on the cabling. It did crazy things as well. The newer controllers use TTL...
