Hi, I am no expert but a few things to think about. Multiple lead acme screws means you have several threads instead of one so they tend to last longer and are stronger. Rolled acme thread has been

Seth, Yes and yes...sort of a safety issue too! Change the leadscrews to .3" pitch from the .2" called out and you'll travel at up to 40" per minute. Regards, Dave Rigotti Hobby CNC

(Hoping this is on topic) In my quest for constant upgrades to my CNC mill/router/pcb thing, I have a couple of questions: Why would you choose a multistart screw over a single start screw? Are acme

There is a fair amount of info on using Vector with tool comp on the Vector support forum. As has been pointed out you have to use a controller that handles the G40 - G42 codes. You then have to setup

Hi Dave, For Vector CAD/CAM, he needs to use the Draw, Other Curves, Offset. Vector will generate the tool paths for him. I'd also suggest that Vector questions be asked on the Vector forum, you'd be

Having different amounts of backlash in opposite directions just does not make any sense to me. It can differ at varying points along your movement, but I think it has to be the same in both

Hi Alan, This question has come up before. I previously suggested using four separate switches, and I'm still of that opinion (I use four switches). Why not just use a little 4PST switch (also

Hi Roger, Foam? With an endmill cutter? Probably NOTHING! Foam or wax should be EASY to cut. As long as you can move the ways, you should have no resistance! I think I'd shoot for wood, anyway. Never

Hi, Yes, digimatic and 'SPC' are different specs, SPC is often proprietary and not well defined for the customer. I used a digital storage scope and examined the outputs at 1.00" and 0.00" to figure

I'm using TurboCNC which allows for backlash, but am worried that an axis might have more backlash going one direction than the other direction. Has anyone noticed this? I have extra ballnuts to

of Both of the products you mentioned are Controller programs that are made to take a finished CAM file and drive the motors. I have used both and settled on the Master5/Mach1. If you want to modify

Congrats on finishing your conversion! Since G40-42 aren't supported yet in TurboCNC, that might explain why the holes came out a bit large. I don't own a copy of Vector, so perhaps Fred Smith or one

This topic has drifted away from the purpose of this list and is now OFF TOPIC and is to be dropped. This list is not about cutting things it is about building converting machines for

I should have been more specific. I wasn't worried about the motor exploding at high RPM but was definitely concerned about the spindle and brake drum assembly coming apart at high speed. You

Wow, that is some good info, thanks. I have read that the import scales, such as those from JTS, use a completely different SPC format than the Mitutoyo scales. Is that true? If so does that mean the

Alan I did this same thing. The only problem that I encountered was if one of the geckos was not powered it would drag the whole disable line down and shut off the others. Found this the hard way! Ray
