Im new at this of the cnc world, i have a question and hope somebody can help me, i have a cnc rpouter, the spindle is controlled by a vfd, in the display of the vfd when is working is showing n and a four digit number, in the manual of the vfd say that n is operstion speed, i attached picture of the manual, my question is operation speed is equal to rpm in the spindle divided by 10 because of the four digit number? for example if the vfd show n1596 is equal to 15,960 rpm? i attached photos of the manual and the vfd showing the numbers

may i ask you another question, if my machine is in metric, the tpi need to be divided in 25.4 in order to get the tpi in metric right? so if i get 2540 tpi will be 100 mm steps per in metric, am i correct?

thanks a lot for your fast reply, let me confirm that dsta and ill let you know,the ratio im still confirmthat and the driver is leadshine driver im searching for the model so i can know the microstepping

sorry for this but pith of the track do you mean the number of teeth in an inch in the rack right? and what do you mean with bely redution? if my reducer gear box have a belt? or something.

Again sorry for the question, i just want it to learn more abouth this.

The calculator should get you going but its easy enough to work out yourself.
10 TPI screw would equal a metric pitch of 25.4/10 =2.54mm

So to calc it will depend on what stepping the dip switch on the drive is set to but we will say 8 for this calc

200 steps for motor, multiplied by 8 microsteps for drive =1,600 per motor rev, assuming no gearing between motors and screw the pulses needed to turn the scrw one rev would be the same. So one rev of the screw moves the axis 2.54mm and it takes 1,600 pulses to do that so 1,600/2.54 is 629.92125965 which is the amount of pulses (steps) required per unit (mm in this case)

sorry for asking but im nwe in this and i want to learn, how to get the info if my machine doesnt have leadscrew, my machine have rack and pinion and a reducer gear box, how do i get the tpi or the number to get my math going? in order to use the calculator.

Thanks for the time

thanks for the repply, the rputer is accurate if o do a square of 100mmx100mm the results is a square of 100.007mmx100.007mm, that a pretty good for me, the problem now of the rputer is that if i hit the go to zero button the machine move very slow to go to zero, the jog speed is fine but when i hit that button the speed reduce a  lot, in the home limits the speed is in 100%.

And the other problem is the auto zero tool, the sensor is dettected and working but when i use the tool the z only go up like 10mm when the sensor is 15mm and that value is in the script that i upload in the software(Mach3).

General Mach Discussion / Mach3 Help with chinese router

I need help with chinese router config in mach3, the xml file that the provider sent me is bad in config, i fix all of the mayority of the problems (well i think i do) but when i make the changes in settings like change the z axis because is working backwards and use the set per unit tool in the settings tab to fix the precision problem the jog speed of the machine will go way daown, like 20% of the orignal speed and in the tab of the jog speed the percentage is 100%, i really cant find any solution.

I use a 1325 cnc router connected through usb to a mxk-IV card to a windows 10 surface pro.

Any help would be very muy appreciated
