On paper, it appears I can use a mechanical relays normally closed contacts and let the contact spring act as default on/clamped. The SSR could just drive the relay coil. One less output pin. You...

Hi. The Mach3 output, which activates a fixture clamp, deactivates with E-stop. I want the workpiece to stay clamped after E-stop. I also need to activate and deactivate clamp with a Macro during...
I am adding a 4th axis to my Mach 3 driven CNC. I need to swing 45 degrees from 0 each direction and can, by using a lever switch, use one limit for Home, --A and ++A . The question is, Can I...
I see that these are properly called tool forks not tool holders.
Can you just use a round pocket for a tool holder or does the standard holder help pull out the tool, BT30? Going strait down into the holder saves space and avoids conflicts with the dust boot....
I have a 30 minute NC program and need to re-home my 3 axis at mid point, hands off, using code. I miss enough steps that the end of the cut is out of position. If I slow down for accuracy, the time...
My open loop machine (using Mach3) when running at its top speeds (325/400 ipm, 10,000 plus line 3d Carving) will miss enough steps to cause some alignment problems in subsequent operations.
I...
I just got a reply from WD bearings and they thought 47N preload, with the usual disclaimers of course. I set them for about 67N (one spring) they were pretty noisy but I'll see how they break in....
I'll give it a spin, Thanks all
The working end of the spindle is back to face(not in opposition). The loading force is a smaller AC bearing on the other end pushed outward by a pair of wave springs. The springs when compressed...
Thanks, I'll check it out Tuesday when I have all the numbers. All the specs I've seen are for either matched sets installed as shipped all flush. If I ordered a matched set (probably wish I had)...
When the bearings arrive I'll see if they will work this way. There not matched but with some careful measure/hone/sort/shim I might get it. If they clamp together with 0 end play and low friction...
Its set up as you said, only one spring for the small end which functions as both preload and temperature expansion. The two hard end bearings were set up tandem fashion where the shaft needs a...
My tool end angular bearings(2) have a catalog preset range but the outboard angular bearing(1) has a smaller preset range. Set with belleviews and spacers. If I use the larger numbers will I wear...
Thanks, I got it to work with G28.1 z0 ...G28.1 Y0.....G28.1 X0. three lines. Just to check, I unpluged a motor and pushed the head around and re-homed. I still can not get the X home (two motors)...
Mach 3 .062 Specifically I would like to know if I can write into my code a re-homing routine mid program, probably between the rough and finish cuts. I am just starting with G code and VB but...
Is there a hands off method to program a home position re-set sequence in G code to pick up lost steps? Homing on the fly? Thanks
Got it going today with touch plate via BOB pin and Mach Script, works great, took 9 hrs but needed to confirm a lot of BOB parameters, make a plate and firm up all my grounds. Thanks again
Thanks, Just the input I needed, what previous poster were you referring to using the auto zero script.
A new build CNCRP, Mach3, EthernetSS and PMDX126.
I am configuring my Z for setting tool height and realized I had previously installed a hard mechanical limit switch wired to the E-stop (trips...
Proximity lateral vs head on
I would like to set up an inductive proximity sensor where the target moves in from the side. If used as a home switch will it be any less repeatable than a head on...

Given: I make a decent Mach3 probe, how can I get this into MOI (Moment of Inspiration) for cleanup, from MOI I usually Save/Open to Meshcan and Save/Open to Mach3 without problem? Free solutions...
