New Rebuild on Sherline Chucker Lathe & New build on 5400 mill

[BillB]

Hey all got the probe working, turns out I forgot to jumper my new connections on the 24v & com connections at my terminal blocks. Just overlooked that. I did a few probing tests it’s working but I need to calibrate and dial it in I guess. Doing an inside bore probing results in the x y center being off. Reviewing manual for calibration.

Now on to the lathe tool touch and get that one wired and working.

Thank you guys for all your input and help.

Hey all, Working on my Tool touch for the lathe, have it wired up and yet again not working. Here is a video, & report. What I'm I missing? If I do a tool scan I get a unexpected probe contact probing cycle canceled error in the control.

I told you to jumper COM not OUT in the plug

Out connects to Probe Tripped, COM to Probe Detect

This sets Probe Detect if the Probe plug is plugged in, works not if the Probe is permanently wired.

The way you did, it switches Probe Detect when the Probe is tripped, this will not work.

Cool, now you can start making parts

Ya getting really close, gotta finish the final wiring on both TTs and probes on both machines, and "I THINK"????????? I'm done. OH then finish learning CNC lathe work...... then make parts. This whole build (2 machines) only took me about 10 months.

I found, traveled to buy, bought, set up, tooled up, and milled about 8 parts so far on my new Tormach 1100M mill in about 2 months.

Sherline builds, 8 months

SOOOOOO glad to be almost done!

Hey all, On my Tormach there is a calibration procedure to adjust probe tip runout. Basically probing a fixed surface and making adjustments in Path Pilot control and adjusting the set screws on the side of the probe to dial it in.
I’m assuming this is pretty standard for VMCs and knees mills to dial in a probe.

Is there a similar calibration method for CNC12 to dial in the probe tip for mill by using the probe to probe a surface and make adjustments in the control and or give you a sense of how much to adjust the set scores on the probe? OR do we only rely on mechanical adjustment on the probes set screws via test indicator?

OR is the only method to use test indicator on the tip of the probe? I have tested doing this on my lathe probe and its pretty tricky to get the right amount of preload on the indicator without influencing the probe tip. I have a disk end on the lathe probe so will be much easier than the mill probe with a 2mm ball. The slightest preload has some degree of effect on the probe end no matter how little preload. Are seams really counterproductive and uncertain because the probe spring is fitting the indicator arm? ?

Now I’m sure it doesn’t help that I only have 30.00 Amazon indicators. I’m sure a higher-end one would be better but that’s what I have for now.

Any input welcome on this.

run out of the probe must be mechanical adjusted.

Use a lever type indicator like this:

That’s what I have. Did u find any additional documentation for the probes we are using from Ali Express regarding adjusting the run out? All I have is from the web page and there is nothing on how to to it.

Did you loosen all grub screws 1st OR just tighten the one on the high or low side? They seam really tight with little effect on adjustment

Read from page 13 :

Works like any other adjustment with 4 radial set screws.
