Upgraded my 8” Z to the 12” and it comes w/a “drag holding brake” to prevent exactly the unpowered movement of the spindle you describe. Corey explained its use - you might ask if it can be...

Neat idea, though I just permanently attached the wire to a metal component and just zero it the usual way.

I have a Smooth Stepper so at Jay's suggestion I added a breakout board -...

I've done it. It's pretty straight forward. I can answer specific questions and Jay at JTech is a wizard. Great guy.
Good luck.
Scott

Point taken. Thanks for the clarification.

Confused - in the picture it shows 120v and .91a. That should equal 109.1 watts yet the readout shows 57.7 watts.

warrenb - thanks for your suggestions. I will check as you suggest. Scott

Goonk - thanks for input - checked that as well.

FWIW I did a re-cut this AM and it ran normally. Not sure what happened but thanks for all the help and for allowing me to waste your time with...

ger21 - units set to inches in Mach3 - I see your point about the MINUS .2 PLUS 2.28 discrepancy. On the pic of the Mach3 screen I uploaded I noticed the Z DRO has a green border around it while the...

ger21 - my mistake, G43, and it also does not appear in the .txt file - all units are set to inches unless by native units you're referring to a Mach3 setting, will need guidance if you mean Mach3. ...

ger21 - no g45 code included and no way to indicate tool length in database.
cncjack01 - will try this tomorrow and report back
nlancaster - listened very carefully at 100% feedrate incrementally...

Hi guys, need a little help please.

Doing a roughing pass on a 3d terrain file and when the second pass started the machine was cutting deeper than the g code indicated. I've included screen shots...

You might try Ugra CNC; I bought my 2.2kw (3hp) from Andy before CNCRP offered theirs. Water-cooled - ~ $1000. Excellent after sale support.

I'm re-asking my question about rastering technique as it applies to a CNCRP 4824. Does it matter whether two motors move the massive gantry or one moves the (comparatively) light Z-assembly with...

Thanks!

Thanks for getting back to me so quickly. I can re-work the question to include a reference to CNCRP if you prefer but, yes, may I ask you to move it back to the CNCRP sub-forum? As an aside, where...

May I ask, as the original poster, why this posting was moved and to where? The question was posited to the designers of the CNCRP machine. Is this the wrong forum for such questions?
Thanks. ...

Hi all,
I'm doing a 3d roughing cut which will take several hours. Is it better (easier on the motors) to raster cut moving the heavy gantry back and forth using the slaved X,A motors with the Y...

Which youtube video? Thanks.

Great! I'll check w/them for the particulars. Thanks. Scott

I agree that Cory (and Ahren of course) provide stellar service and troubleshooting. You mentioned a 5th axis - did you mean 4th axis? Also, I don't see a rotary axis mentioned on the CNCRP site. ...

Appreciate your input. Thanks.

If I may, how exactly did you swap axes? Which pin assignments were swapped? Any cable swaps as well?

Three quick points.
1) The table height (and subsequent center of gravity) should be as low as possible to avoid amplifying any movement - hence my comment about table leg length. If you get...

Depending upon now long the table legs are, you're likely going to need some diagonal bracing to keep the table from shuttering with each short, quick movement of the gantry. I know yours looks...

Good find! I missed those. You're right, not too bad.
Thanks for the info. Scott

Wow! I checked around. That has to be the understatement of the month "certainly not a low cost option." Thanks for the info; maybe I'll just build a shield around the ends and hope for the best. ...

If I may, where did you get the right angle plugs for the sensors? Seems like a great idea.
Thanks. Scott

Just to close the loop on this issue. I spoke to Ahren a few minutes ago and he discovered the sensor at the A-slave end of the gantry wasn't working as expected. I swapped it out with the sensor...

Thanks for your input.

By motion controller are you referring to the Smoother Stepper? I used the SCU v1.1 to configure it. Could you be more specific?
Thanks again. Scott
