Hi RL,

In my other build log, my larger 49x62 machine's gantry weighs about the same as yours and the NEMA23 Keling 495 oz-in motors KL23H2100-30-4BM (Dual Shaft) I'm using are more than adequate for the job. The NEMA23 Keling 382 oz-in KL23H2100-30-4B (Dual Shaft) motors will also handle it I'm sure and are $10 less expensive. You can find them here. For the 382 oz-in motors you should use Keling's 65 vdc power supply because the motors have a lower voltage specification than the 495 oz-in motors. Make sure the power supply voltage you use is within the input voltage range of the driver you use.

I am using the Keling KL- 7220 72vdc power supply here.

My drivers are the Gecko G203V and the breakout board is the CNC4PC C11G.

Using two 495 oz-in drives on the X axis gives almost 1,000 oz-in torque at low speeds to move the gantry around, and it seems to have no problems doing it. I've had the accel rate up to 50 and all it does is shake the work table when it reverses direction. 20 to 25 is where I'm normally running it and there is no noticeable lag time on starts and stops. I have been really happy with this combination of parts and you'll find others here that have also used it with success. You will easily see jog speeds of over 1,000 ipm.

This is for sure a hobby where you can spend as little or as much as you have available. There is a lot of satisfaction in building your own design and making it work well. Unfortunately many of them probably never get completed because of cost over-runs and the amount of learning involved to do anything useful with them.

My larger machine uses standard 1/4" x 72" CRS flat stock for the X axis rails and I have 62" travel once the extended carriages and router overhang is accounted for. The gantry allows a little over 49" travel so that I can cut MDF edge to edge. Future plans for it is to build a 10' long steel frame and transfer everything over to it and regain the use of the work table.

I also have more upgrades planned for the 25x37 machine in this thread.

But rather buy right componets rather than wrong ones and
then half spend more money!
I was Self Employed cabinet maker for 30yrs mye wife wanted me to quit do to back injury!
So went work as designer for store fixture company 4 yrs ago!
My wife past away this last Nov. from cancer and youngest child
graduates from high school here in week and is going into the airforce.
So Iam wanting to go back to doing some form woodworking as bussiness!
Have tablesaw,bandsaw,Bench 12" planer,combo edge spindle sander,mitersaw, sanders,drills,scrollsaw,9x32 2HP Benchmill Enco Brand and etc.
So i figured needed to at least have some sort cnc router keep up
with jones as they say!

Sorry to hear about your loss. I'm probably a few years ahead of you and starting retirement now. It just means that I'll pick up speed with this stuff. I have collected lots of woodworking and metal working toys in the past ten years and have been enjoying all of it the past two years building the two CNC machines and other projects. My part time contract work lets me be as active as I want to be, and still pays the bills.

I was in the USAF also. It was good duty and taught me enough electronics to make a decent enough living afterwards.

You'll find a lot of ways to use your CNC machine. Some of it might even pay something for your efforts. Maybe you can find something that can become a paying service for the local cabinet shops, since you already know their business.

I will start build post as soon as find mye digital camera!
Thanks for your reply and hope to get little help with wiring electronics
from you since you have already done It will go after same componets
you bought!

Have fun in CNC world thier amazing machines to watch!

oldhack has used these components also, and has jogged his machine at 1,800 IPM. His is probably better aligned than mine. It can only get so close when using a wood work table for a frame like mine. By July I should be able to order the steel for my new frame construction effort.

Will help any way I can. There are many folks here with much better knowledge of the subject though. I don't get into the excruciating details so much as I just build it and see what happens. And I read a lot of the build logs and discussions. Some of it has even stuck in my head enough that I sometimes feel "dangerous".

Dam can,t find it only one other place to look dam crawl space storage
have to move few shop tools to get in there and fend off few Spiders
Also ordered Arhens Extended Linear Bearings Today!
Signed up to Work Overtime next Sat and Sun that be extra $400
almost pay for those 203v

Good to hear it. You won't be disappointed with the performance, and there is amperage to spare for larger motors later.
