John,

Would you paste the actual code you are using here.
CNC code is picky about format and order of execution. It seems that you are using a T4 and a H4 on the same line of code. I think this...

When I look in the Series 2 user manual, it has a good step by step troubleshooting procedure for the Axis Drive Sub-system.

It is what I would try with a difficult problem like yours.

figured it out.

I second about the motor coupling. I was loosing position on my Z axis. I tightend the coupler and I was still getting slippage.
After removing the coupler I could see that the coupler ID had a very...

Ray, PM sent about KFlop

OK, I guess that was kinda boring. I changed the video...removed alot of the screens and add afew cuts.

Thanks for the suggestion.

The other day I was doing some helix bores that I needed to hold about .0005" in aluminum for pressing in a bearing. Normally I adjust the bore size in the CAD/CAM and repost. But after the 4th back...

That's a nice setup!!!.
Now that you have lived with it a few months is it working out OK? May I ask a few questions.
Does your coolant tray leak along the welds? Mine leaks pretty bad even with...

Your the master...that works great. After un-checking gouge check in lead in/out it's just what I needed.

Thanks

I run 1/2" 3 flutes in aluminum almost exclusively.

For roughing contour I use RPM 3200, 50 IPM, .15 WOC, .35 DOC
For slotting 3200, 37 IPM, .15 DOC

Were you getting any chatter during the...

This works OK but the lead is not long enough. My controller needs at least a cutter radius.
I realize this may be impossible if the cutter starts inside the bore. But if I had clearance above the...

I see what you mean about the Operations Manager. None of the managers have short cut keys for there internal functions.

The lead in is more of an issue with the Mach 3 controller. It needs this...

That is a very interesting option. Maybe make several different size trays, filled with the alloy at the ready...thanks.

Here's some pics of how this project is going.

Drilling a turners cube...

I am using a 1/8" 3 flute to a depth .300". I should have used a 1/4" 3 flute because the 1/8" took to long.
Yea, I really like my .22 S410 E also. Some of my freinds think it's a toy till they see...

Good stuff here, especially the StrutCAM video. When I have time I think I’ll watch them all and try and apply the techniques to MasterCAM.

It looks like if an un-interrupted outside chamfer is...

Excuse me for being away for the day. There is a lot of good information here that I wanted to give a try.

Gerry, thanks for the pictures. I had stuck in my head tabs with holes in them. Then...

Steve, thanks for link to monster-jaws. Last time I looked for aftermarket jaws, I didn't see the 5" jaws. At that price it's not worth making my own anymore.

The reason I was resisting going to...

Just wanted to give a quick update.
The method of holding parts using CA has proven to be unreliable.
Some times it holds and other time not.
This part and plate had an acetone cleaning, a 24...

If I may offer this, here's my the way I select cutting parameters for my PCNC1100.

I use a freeware calculator called ME Consultant 2.0. It's on a few download sites when I Google it. It has a...

Here is a formula I found in SPC thread mill catalog for adjusting the feed.

(Major dia. - tool dia.) / major dia x NAFR = AFR

NAFR = not adjusted feed rate for selected tool diameter.
AFR =...

+1...with his resume of couse :D

My series I machine was also having the same problem you described. It started about 6 month from new. I use to fix it with a shot of WD40 and working it into the switch with a long screw driver. But...

This is how it generally works for me too.

I have a place that I do contract engineering protypes for on my PCNC1100. I do a few at first so the engineers can see if it fit and performs as...

What is with the fragile egos on this forum. It seems to get in the way of just simply answering the question.

My experience on my Series I PCNC1100 with VFD upgrade is this:
The spindle power,...

I only know Mastercam so I can't give specifics about SprutCam.
My guess is:
Was there a different fixture offset assigned to each of the CS's. G54 to CS1, G55 to CS2, etc. I've had this happen in...

Cool, glad you like it.
Yes...the first cuts were my tried and true roughing parameters before the new collet. It left a little in reserve for full width cutting that can happen in a profile and...

Just like alot of things, tighter doesn't always mean more clamping pressure.
I think I've increased clamping surface area and it's why the improvement.
But all I can say is I'm not a newbie at...

Was messing around in the garage today and thought I'd make a vid of some test cuts. The cuts at the end are heavier than was possible before the PDB.

TTS Pull Out Test - YouTube

I have read on this forum that other people were also having pull out issues so here's how I fixed it.

Before I installed Tormach's PDB, I was able to remove aluminum at a rate of about 3 cubic...
