I'm working with a client who wants me to mill some fixtures that require 3D milling. He can provide any of the file types that Solid Works outputs. I've been using Cut2D, but Cut3D seems to be

Most steppers are 200 steps per revolution, for 1 inch it is 10 x 200 as the best place to start.?M. Wolgamott www.cnc-n-signs.com?for more Digital 3D solids, eBooks and G code Sign up for new

Did you mean to use "+"? Rick

# of pulses per motor revolution + lead screw threads per inch + any gear ratio between motor and screw = pulses per inch Mach3 then has a calibration to test that accuracy under CONFIG MOTOR TUNING.

I am NEW to CNC and am struggling. Can someone tell me the number of steps to use in the motor tuning on Mach 3. I am using a 1/2 10 acme lead screw. with Nema 23 motors Thanks in advance for your

Nice write up but you miss the critical point of backlash. Yes, Mach will do the right calculation and move the extra steps, but there is a period of time when this is happening that the table is, as

Hello dears, just for accumulated knowledge I will tell you this piece of information. after agony installing/uninstalling windows and mach, I solved the problem that made my steppers low torque, the

Repeat exercise when cutting. Make a rectangular part with a circular pocket in the center, then measure it - Diameter, depth of pocket and concentricity then outside dimensions and squareness. Then

I am just starting to learn about Computer Numerical Control (CNC) including Mach3 to drive my hardware. One of my first baby steps was to set up the backlash parameters. These are important because I

Dear Hannu, Thank you for the response and the valuable information, please note that: - My DIY lathe is using linear guides (see attachment). - I use 4.2A NEMA 23 stepper, 2.5nm. - I use an ordinary

The mill and the lathe may have completely different step values .. these depend on the gearing, if any, and the microsteps, if any. Also, a lathes saddle is usually heavy, and usually stiff, because

measuring between any two phases is 129 volts. there is no manual for the 110 volt version. the web site says 20 volt output and the inverter is sold in a package with a 220 volt motor so i thought

Hello dear mates, I need some help in tuning steppers in mach turn controlling a CNC lathe, when I rum Mach mill, and after a precise calibration process, the steppers work just fine in such a great

Hi Spencer, If they say it should output 220V with 110V input then it should. When you’re doing the measurement, are you measuring the voltage between any two phases of the output? (You should).

i talked to the guy at auto tech who has the same setup on a machine of his own. he said that the 110 volt input inverter does put out 220 volts but i think that is not true. i get 129 volts on the

i just called automation tech and the guy who knows about this inverter is going to call back later. he supposedly has one working. the guy i spoke to said that he thinks the web site is wrong and

Spencer, Exactly what type of inverter did you get for your motor/spindle, do you have a link? Andy and Brendon, Thanks! Turns out they're not quite as rare as hen's teeth but still not very common as

will be interesting to see what automation tech has to say tomorrow.

Henrick, The specs for the 110volt drive (online) say it produces 220 3 phase output and it is normally sold in combination with a 220 volt motor so i assumed that this was correct and that there was
