I have been in a huge bind. I bought a 3-axis system from a guy on the forums and he has been a big help. I first got a 3-axis system and for over a week we tried too set it up.

I'm using a Taig with 3: http://www.kelinginc.net/KL23H276-30-8B.pdf Stepper motors.

I thought I was going too be able too get at least 30 Ipm. I can't even get like 20 IPm, not even 15 IPM.


I set it up in EMC2 with the xylotex settings, but no help.



Does anyone have any information on this.



I bought a new computer thinking it would fix the problem. Latency: 15,000NS

I too have a Taig with Xlotex board and keling motors that is painfully slow. I have played with many things including the gibs. Oiling the ways and setting them just right made the biggest difference. This alowed me to cut at 10IPM. Which is also my max rapid.

I currently have it set at 1/8 micro steps, or what ever is the highest on the Xylotex board. I am going to try setting it to 1/2 or 1/4 micro steps to see if it helps.

I run mine on mach3 and my old desktop that I cobbled together with an AMD Athlon 2200+ using the onboard PP and a ati video card. I think 1g ram.

One of the things that I noticed on the cheap drives forum (Gecko) is the motor equation for max voltage. sqrt mh*32 = max voltage. On my motors that works out to 83 volts but with the Xylotex 30 is about max and my setup came with 24v ps.

Your motors are 2.2 mh which works out to 47.46 max voltage. If you run them at 24v it is almost half which gives up a lot of power and speed.
From what I have read voltage is what gives you the speed but increased heating. As long as the drive has idle current reduction it is not a problem and do not exceed the max voltage you wil be OK.

I think that you need to run the motors in parrallel to get max speed but someone else can chime in to correct me if needed. Assuming 8 wires from motors.

With the very fine thread on the screws you need a lot of RPM to go anywhere.

I will be selling mine as I bought a full size machine BTC-1 to better match my needs.

To truly run the size of tooling the Taig takes at the speeds the small tooling is designed to run in aluminum (1/8 or so) you really need much more spindle rpm and greatly increased feeds.

I want to say that I am not trying to piss anybody off. My Taig has been very faithfull and is making parts several times per week.

As other have said, run the machine within its limitations and it is a great little machine. Especially when you figure in the cost to purchase.

Just my 1.5 cents worth, inflation you know

Your totally right and it's finally nice too see what I was not the only one.

I am upgrading too Geckos, the new ones that come out in two weeks. The 540's series, plug and play, rate for 50 vdc.

I just want too rapid higher then 6IPM, I know the Taigs limits, but I will not limit it that much....


Thanks for the post.

Hi there!

I am using a HobbyCNC board driving my my stepping motors at 2.5A. When I tried to use 1/4 or 1/8 step. All my motors would start stalling at about half the speed compare to that when I run them using 1/2 step. So, I guess your problem might have come from your using too small step.

If your drive can adjust the motor step, you shouldn't run it lower than 1/2 step.

Just my thought.
