    Table out of square?

    Good morning.

    I recently acquired a 2016 PRS Alpha ATC. I was experimenting with a product that is symmetric. I ran it face up for one operation, then flipped it over for a secondary operation. ...

    This won't work. I have two motors in one chamber on my old system. The vacuum created by the running motors will cause the un-powered motors to spin backwards, allowing air in that way as a...

    Hey Red. That very well may be the case. My vacuum numbers are very similar covered vs. uncovered. Also, I just noticed that the v-shaped support under that area is missing all the bolts on one...

    I have the pressure plate on the ATC, but I use the Z-Zero plate on the table.

    I am leaning towards a plenum problem. I just re-zeroed to the table and ran this pattern on the blank table with...

    Thanks for the pic. I've verified with Vectric that the post processor they have for V-Carve PRO is, in fact, the correct one for the ATC. It has all the proper call-outs for the ATC. Anyway, none...

    I tried to use my Micrometer to measure the Z travel. With the imperfect method of measurement it seems to be accurate in terms of the stepper values. It certainly does not explain the pattern from...

    So, I turn the vacuum system on when skimming, which I learned with my last vacuum table. Now, this seems preposterous to me, but I'll go ahead and say it.....

    Is it remotely possible that the...

    Thanks for all your input.

    The guy who sold it to me (and delivered it) helped me set it up. We ran the CN74 program to calibrate the clip locations. We loaded the tools into the collets and ran...

    Yes, I ran the C73 table offset for the zero plate after skimming, and all the bits have been zeroed correctly.

    Z-Depth Trouble

    I'm refining my last post a bit.

    My machine is consistently NOT cutting through the material when it should.

    My machine is a 2016 PRS Alpha ATC. I have skimmed the spoilboard. I program the...

    Since I bought this used, and therefore am not terribly familiar with the assembly, can you clarify a little? As in, what's a "grub screw".

    Pardon my ignorance.

  16. New machine, new headaches - need ideas

    I just took possession of a 2016 PRSAlpha ATC, replacing my OLD (circa 2001) PRT. It's taking a bit of getting used to, unfortunately. I did find out that I have a bad connector on the Z-Zero...

    Yes, that's what I believe as well, though I imagine there is then SOME miniscule amount that makes it through to the air. Can you recommend which oil/water separator to use? Oh, and thanks for the...

    Most of the compressors I see are oil lubricated, which ShopBot says not to use. Can anyone recommend a specific compressor, preferably not...

    6 IPS???? Wow. What depth do you cut per pass?

    I'm probably cutting too much at a time. In 3/4" pine (0.725" actual), I cut in two passes.....basically .375" per pass, but I'm only cutting at...

    Is it? I've been cutting plywood with these bits now for 6 years, with mostly success. I suppose I could upgrade to a 3/8" bit.

    I do also use upcut spiral bits often, but they require more...

    Fire in the hole!

    So I piggybacked this off another thread, but thought I'd start a new one.

    I've had my router spontaneously combust a few times. The first time I was plunging holes with a compression bit, which...
