I wish I could share the files, but that was my work computer - which I no longer have access to. No more Solidworks for me, at least until Covid is under control.
As I remember, I could not...
I was able to get things working ok using my existing Onsrud/OSAI post.
I had to manually swap in a slightly different header and make sure arcs were absolute IJK with G90.1, at least for my...
Hi Michael,
I was wondering if I could get a copy of your MC/Mach3 post?
Running Mach3 mill at home and temporarily don't have access to the big Onsrud at work.
Could possibly get...
I've been on vacation for the week and wasn't getting updates on the discussion. I am happy to troubleshoot the post processor and try to get this working.
It was intended for exactly these...
It looks to me like you've done everything correctly! The one thing that jumps out is that your post has this section that might be used for XY moves.
With Mach, it uses the 53 section, but I'm...
I can see the extra debugging information, but not the information I'd expect to see if tabbing was happening.
This is the critical section. The program knows that it's the final contour pass, so...
I know you've tried both options, but for the simple part, I think you want the first "Enable G01 tabs" option selected.
The item is ~2" square with radiused corners and 1.5" G01 straight line...
I'll try and help work through it, but I haven't thought about this in a long time!
The downward Zfeed comment indicates that the post processor has found the final Z pass and will be trying to...
I'm also interested in this lathe, but willing to cut Grizzly some slack with marketing/documenting a new product.
The catalog might be vague, and the website product page misleading - but there...
Yeah, I agree with Matt. The big companies will use GPA and university as a filter because they are overwhelmed with applicants and need a way to quickly reduce the field. Smaller companies or...
Start with what meets your needs and fits your budget. DIY machines can be tweaked and upgraded because you'll know every nut, bolt, screw, wire, etc. Focus on a very solid frame and accurate...
Yes to all of the above. Wired bipolar parallel, the inductance is 6.8mH, so the ideal voltage would be more like 32*sqrt(6.8) = 83V. I was using an unregulated 72VDC supply at 10A, so adequate...
Making your own bearing blocks is not complicated, but I wouldn't say it was fun. A milling machine would make short work of this, but I did everything with my router and cutting aluminum is a bit...
I like this paper tape #505-2521 from Enco. I use a lot of it for small parts and hard to hold items.
With thin plastics I'd recommend a decent amount of tape and use a straight bit (no upcut) to...
I'll second what louieatienza said about the couplers. The standard Lovejoys you posted are too sloppy for CNC. I had a set and couldn't use them.
I then went with aluminum helical (nice) but...
I just helped a friend do this. You leave the machine setup in inches, but adjust the steps/inch in the motor tuning screen. So, with 10x microstepping (2000 pulses/inch) and 5mm ballscrews, it was...
I was lucky because I found them on eBay, pre-drilled and tapped on 60mm centers. I had no idea as to the machining costs, but it sounds like you found a good solution.
With a stop setup on your...
I haven't seen a torque curve for that particular motor. Gecko might have one if you called them up. My impression (from looking at Keling specs, etc) was that the 270 oz-in and 380 oz-in motors...
That is a versatile motor/driver package. You could go with fine or coarse screws and still have a nice balance. If it's important to have 1000 steps/inch resolution, then the .2" (or 5mm) is a...
Rick, the .2"/turn lead has been good, but I (personally) would go with something coarser next time around. For my machine, with a 25x32" work envelope, a .5"/turn lead (or probably 10mm, 12mm,...
It's in the PDF catalog. I think the part number is 8900-36 for the 36" lengths of undrilled/untapped 15 series nut stock. I sometimes see it on eBay in the 8020 surplus store, which is where I...
You've got a nice design there, and I'm sure you'll be pleased with it. It's very elegant with good lines. A minimal number of pieces and I like the idea of water jet cut parts with the 8020. Much...
Here are the files from post #34 converted to IGS format. Just the mounting plates and other misc small parts.

I just haven't had the time to look at it. I will eventually get around to it, but it's a very low priority right now.
I have a workaround by using the VFD programmable input to control on/off...
If you're just after experience with CNC and tackling the learning curve with CAD/CAM then I would say build as cheap as you can and enjoy it. I wouldn't plan on it being a great money maker because...
Thanks Sandy, that is helpful. I will be on the lookout for a quality vernier and I do understand how important a repeatable setup and test procedure is for accuracy. I'm not expecting to find...
I have really enjoyed this thread. I always wondered how accurate my rolled ballscrews are without having an easy way to measure/verify them. I can take small measurements with my 6" calipers, but...
Gerry, I've been using that same line on my wife for 15 years and strangely enough my shop is better furnished than my house! Eventually she will catch on...
Yeah, very nice! A solid bench is a great foundation for the machine. My bench is a little light duty and I keep thinking about something more along these lines. You might just inspire me to...
