Your design is very similar to the very popular PrintNC design for DIYers. The PrintNC is highly customizable, is made of bolt on steel tubing and seems to have large following and supportive...

This guy used the Bell Everman system on the MPCNC. I like his belt tensioning mechanism.

BBMNet - thanks! It was indeed the mechanics. The set screw on the coupler for the ball screw end was slightly loose and had a little play. This caused a slight slippage on each directional change. I...

I am running a GRBL controller with the infamous TB6560 driver with Nema 23 motors. Lately my Z axis will not always return to the zero position. To reproduce the issue I have a gcode file to simply...

Hi Steve - those bowls looks awesome! So far, I haven't tried anything with a contour on the Z axis. I will try that soon. I need some try some cuts with a ball end mill. Funny thing is I've only...

had fun with the CNC again this evening. I cut out 8 simple knobs.

I been playing with the CNC machine for a few weeks now after almost a 2 year hiatus. The latest upgrade has been setting up a bluetooth module on the arduino board and controlling the cnc...

Just had my first born 2 weeks ago. Hobby time is pretty limited.



This would be great addition! Also a setting to mill pockets from the center out would be useful.

The main issue with...

How do you specify the stepover for pocketing operations ?

I got GrblGru running on Linux Mint with the following procedure:



start up PlayOnLinux (POL)
start the wizards to Install an Unsupported Application
use wine version 3.7

has anyone gotten GrblGru to run on linux using wine ?

Thanks for sharing the pics and your data driven methodology :) . I particularly like the BSA and Bulls head signs. Looking forwarding to creating better products as I gain some experience.

First...

I compeletely agree. I enjoy this part of it myself.

Don - do you have any pics of some of the work you've done with your bootstrapcnc ? I'd be interested in seeing some of the finished work. Do...

GRBL is great! Intially, I had the same jogging issue with GRBL. But version 1.1 of GRBL supports real time jogging. I use "GRBL Controller" (an Andriod App) as the gcode sender. See comment 61 for...

Thanks Don! Overall I think your design is great for an inital hobby CNC am very pleased with the machine. I have gained a tremendous amount of knowlege and the satification of building your own CNC...

below are the a few pics of the completed box.

Additional updates:


upgraded to the 24 V power supply and can now jog at 80 ipm which is faster than I need
cleaned up the wiring and...

I just finished my DIY CNC router and have been using bCNC and UGS on Linux Mint. A few days ago I stumbled apon an open source Andriod app called "Grbl Controller" (available on the Play Store). I...

I've been working on my first project - a 80 mm x 80 mm x40 mm box. Here are a few parts cut and fit after a little sanding. Machine is working well so far. My feed rate was set to 900mm/s. Currently...

Thanks Fred, my acceleration settings were indeed at the default value. Increasing them helped.

I'm in the process of creating a spoilerboard with T-tracks for clamping. I plan on surfacing it...

Got my first test cut!

Bought the Makita..router mount in progress..

Thanks for the input on the wiring!

router options:

The original plan was to go el cheapo and use a Harbor Freight router I picked up from craigslist for 25 bucks The problem is that it has an...

I'm in the processing of clearing up the wiring and am concerned about elecritical noise. Any tips on which type of wires (shield /shielded/stranded/unstranded), guage, and connectors to use for the...

Hey Fred - I'm no expert as i'm still working on my first machine but I have read that rails for the Z-axis should be on the side of the router plate as it adds stiffness. Any paritcular reason for...

Thanks Wizard! Agreed - there's nothing like starting up a machine you built from scratch for the first time. The credit for the design goes to Don who created it as well as generated awesome plans...

Anyone have GRBL's Jogging mode working with a gamepad on linux? I've been reading up on using antimicro for interfacing the gamepad with a UI. No search hits on cnczone.

it's seems like it's against my objective of keeping the cost down, but patiences costs time and time costs money. I rolled the dice and ordered the same ballscrew from the same vendor (banggood) ...

Attached is the breakdown of the total cost so far. $540.

All 3 axis are moving! At the end you'll notice I need limit switches :)

Last weekend I about to install the x axis ball screw and noticed it has a pretty bad wobble. The 1 m long screw was bent. I ended up ordering another one and got it installed.

Today I wired up...
