Building or Buying a Wood routing table.. Beginnners guide.. / Cnc router pre build preparations.

« on: March 09, 2017, 07:55:40 AM »

So I've decided to build my next cnc router, my first is a kit I had ordered and put together. I am building the base from welded steel tubing with some cold rolled flats for rail beds. And a mix of steel and aluminum for the gantry. I'm trying to get some tools together like dial indicator, straight edge (eeek I dont like the prices), twisted wire for straight edge..... can anyone that has been down this road recommend any usefull tools or inspection equipment that would be usefull in the process? Any recommendations will be appreciated. Thanks all

General Mach Discussion / Cnc router motor upgrade opinions

« on: March 02, 2017, 02:34:04 PM »

I am looking to upgrade my motors on my router. Does anyone use the hybrid stepper motors with encoders? I like the clearpath motors but there a bit out of my budget. I have nema 23 425oz/in motors without aa data sheet. Does anyone have any suggestions for motor upgades? Good couplers to use on motor directly mounted to shaft of ballscrews in all axis. I have 5mm pitch.

General Mach Discussion / Hybrid stepper motors from e bay

« on: November 02, 2016, 07:57:07 AM »

Does anyone have any experience with any of these brands? Im fairly new to cnc. My machine is a kit with nema 23 steppers. I recieved no info on. Ive been using machine about 8months now with little problems until i did some test wood joint cuts and im losing/gaining steps. Could that be my drivers going bad? It seems im losing power to my motors. The electronics i have are all cheapos from china so maybe the bob not giving quality pulse trains? I increased steps per unit and seemed to be no help. I machine hard woods and some aluminum, what is a realistic feedrate/ cut depth for a spindle that spins 24000? Thank you all for any suggestions.

Newfangled Mill Wizard / Some kind of error im making when loading a job.

« on: July 03, 2016, 04:06:32 PM »

My tool table in poc when opening mach mill. Then i load job and get slot width must be greater than tool diameter. Then open tool table to no tools. Im not the best with computers and had a minor problem installing and could the issue be that im saving my jobs in the wrong mach mill that might be the one i didnt install correctly. I thought i checked for this and i had to stop for the day. Job completed but wanted to find a solution. The last is the jig i made for welding parts on 3 dif. size rings.

General Mach Discussion / New cnc router kit build

« on: May 25, 2016, 07:44:54 AM »

I got this machine as a kit and have made a number of things for it. I have the famous huanyang vfd and am contemplating ordering a rs485 to usb to run modbus for huanyang on mach 3. Can anyone guide me on this topic? Also i am in the process of wiring limit switches and homes for the x axis and y which the y is slaved to the a axis. I have concluded if i wire the limits in series with e-stop that leaves me 4 outputs on b.o.b. ...... I would use a switch on both y and a axis motors and one for the x axis home. That leaves me one output for making a auto tool z-setter. I have mechanical switches because I plan on doing metal also. Im out of my shop now so I'll post some pics of everything when I get out there.

General Mach Discussion / New guy to cnc world

« on: May 04, 2016, 10:26:04 AM »

Ok well ive just recently assembled the cnc router. I have just a demo version of mach3 for the time being and im having a problem with calibrating the axis. I chose to do it in inches and have 10160 steps per unit. My dro is set in inches but reads in metric. Is this just locked for the demo. If i change the steps in calibration to 4064 steps per unit it works accurately in metric. Theres got to be something im missing here. Thank you all! Tim
