Looks great! I like how you did the X axis. I bought my Acme screws from Enco. They were very cheap and work well.

Why drill and tap all of the screws? I only did that for the adjustment blocks and used drywall screws with glue for everything else. For the gantry I added biscuits to help align it.

I've never used Freemill but a great free route would be Sketchup with the Phlatboyz CNC plugin. I've used it before and it works well.

When you get the CNC up and running don't forget to surface...

I wouldn't bother using mdf for the adjustment blocks. If you can get HDPE use that. I couldn't so I used scrap oak that I had. It worked fine. I just drilled the holes slightly undersized and then...

yes. I use it with my DIY cnc and Mach 3.

I've used a video baby monitor as well. I already had one but you can probably find them cheap online.

Check out the free version of Sketchup and the free Phlatscript plugin.

It's tough to beat the free version of Sketchup and the free cnc plugin Phlatscript. I've had luck using this combination.

Make the window in the gantry, it gives you access to maintain, adjust, and oil the x axis screw and nut. It also makes the gantry a little lighter too.

The "extra" holes in the gantry are for the...

Enco is very cheap and work well.

That was it. I have a custom profile. I moved the files and it works great. Thanks for an awesome app!

I know this is an old thread but I'm hopful that someone's watching. I just downloaded the plugin and when I fill everything in and click Post Code nothing happens. I don't get any code. Here's the...

The HobbyCNC package is a great deal. I use them on my JGRO too.

Sometimes I can be a little thick :-) Wouldn't that just leave more unreachable space behind the gantry? I think if you add to one side you will be taking away from the other.

I used a dado for mine. I think I did it with 2 passes. MDF destroys bits/blades so make shallow cuts.

I know people had success using MDF for all of the adjustment blocks but I didn't. I ended up using oak for all of them. A better solution would of been HDPE or even delrin but I already had oak and...

Thanks for the help guys, I appreciate it. I'm pretty sure the steps/units is OK since if I jog the axis 1", for example, it moves an inch and the Z axis position indicator shows an inch. I'll check...

I have been using Mach3 for a while now with no issues until now. I did something that gave my Z axis a 1" offset. If I want to plunge 1/2" I have to program it (G code) to plunge 1.5"?? If I don't...

The Enco ACME screws are single start. I have them. The nuts have to match the screws.

I just finished my JGRO (Long Island)

I am currently evaluating VCarve PRO and have a question. I would like to carve the BullsHead sample but the gcode it produces puts the starting point of the y axis out of bounds for my homebuilt...

Update:
The build started off really slow. My wife and I are expecting twins so I have been busy setting up the nurseries. The good news is they are done and now I get to play.

I spent the last 5...

Nevemind, I get it now. You used the wood to spin the pipe to polish.

Looks really good. Why are you puting a wood plug in the gas pipe? Is there a benefit in doing that?

Keep up the good work!

Check out Glidergider's build thread. He did it.

I think 1/2" acme lead screws and 1/2" flange bearings are the way to go. No need to mill the lead screw if you don't have to. Do most people tap the delrin lead screws like the plan suggests or do...

Thanks a lot for the quick response! I'll probably end up getting the 1/2" ACME lead screws like everyone else. In that case couldn't I just get 1/2" flange bearings and avoid milling the screws? As...

I am gearing up to build my very own JGRO cnc. I have been going through all of the threads and looking at the plans. I have a few questions though:
1) A lot of people are milling the lead screw to...
