I solved this today!

There's an assembly that holds the lead screw and handle to the machine. I was tightening this onto the machine before threading the lead screw nut. The screw would be stuck...

Thanks for the suggestion,Chris. I took it apart again and ran the leadscrew nut along the screw and it was fine. It seemed to rotate freely through the whole screw. Since the slide and saddle...

Hi,

I am having some issues with my G0602. My cross slide is stiff when I begin to retract the tool (think larger radius).

I took the lead screw out of the cross slide and I can move it...

Guys I screwed up.

I was trying to drill out a hole in 17-4 using a HSS drill bit. The bit was 0.070. It would have only been removing 0.004" on each side. I ended up breaking the bit in the...

Yep, they're charging ~$700 for the pathpilot controller which is simply a PC and a Mesa card. I already have a PC available so I'm trying to save some money there. They will send you the pathpilot...

Ah thanks, good to know. I'll probably have to go with the 6i25 because of the available slots on my motherboard. Thanks.

What comes with the path pilot from Tormach as far as hardware? Is it just a PC + Mesa 5i25 card? Does it need a 7i76 or anything else? So if I ordered a PCNC 770 from Tormach and a 5i25 from Mesa...

I don't know that we need all the horsepower but we will need to control spindle speed through the software. I'll have to ask the key stakeholders in the project if they really need more HP or not. ...

Ah that's a good idea. I was worried about its weight. Have you done anything with the spindle? I'd like to have something at least 1/2 or 3/4 HP and variable speed.

Also where do you see the...

Thanks for the info. The Taig did seem like a good choice but the small size and light weight worries me. There's a CNC Taig mill where I work that we use for mold finishing. It's pretty nice when...

Got me. The easiest sensor to include will be a power monitor and tachometer/encoder for the spindle. I assume a platter type dynamometer would be sufficient for measuring other forces. I have no...

Hi. I have been tasked with putting together a CNC milling machine for research at my university. The real meat of the research will be measuring forces and determining tool life while machining as...
