@@CNC4XR7 I checked the averaging of the spindle speed, and removed, and tried different options, but for 10 days now I can’t figure it out, can it be because of the m1076.m1s file? or because of the controller that connects to the LPT port.
I've been pulling my hair out trying to make this work on my cnc lathe conversion. I think it's my breakout board but who knows, what breakout board are you using? I'm using a usb board, everything works great accept the tach.
@@CNC4XR7 I've tried everything from 5v to 24v (my board will handle up to 24v). At 5v mach3 doesnt pickup the index signal even though the led on the sensor is coming on as the magnet passes, mach3 does pick it up at 24v but randomly. When I check the sensor wire with a voltmeter it gos from 0.3v to whatever voltage I'm trying. Thinking of trying a drop resistor? It's like the low voltages arent enough to trigger mach but the higher voltages dont drop quick enough to trigger consistently. Or it's just my crappy usb bob doesnt send data quick enough.
Sam, I love your videos! I'm planning to do a cnc conversion of my G0602. I ended up with a spindle motor that is 3450 rpm (same D80 frame motor from Leeson - 1920257) instead of 1725 rpm (Leeson - 1920251). What do you think about using this motor on the G0602 vs the one at the 1725 rpm speed? Do you think I'll run into any torque issues etc. I don't want to spend the extra money but I also don't want to go through the installation twice if I can avoid it.
I have found over the last couple years running the machine the torque is lacking even for the 1725 motor. I run on the low pulleys and run the vfd at around 100hz to get the higher speeds that seems to help. Not sure that helps. I guess if you have it and cant return or use it elsewhere then try it
I would like to see what CNC looks like and how you adjust to MACH 3, super video, thank you sir!
Your welcome
Love watching your CNC lathe in operation Sam. Big thumbs up mate ;-)
Thank you Aaron
very nice video format! y so difficult make videos from this topic not boring. nice to see you keep doing this way always improving.
thanks
have u been using the threading wizard? if so do you know the benefit of the thread chamfer feature?
Sorry no I don't use the wizzards.
very nice jobe, how to you wiring the encoder with match 3?
1 count per revolution. I have a video on it
Good video!!
What input is the spindle rew control
Conected to?
Index for the Tach If that is the question
@@CNC4XR7 yes the tach or pulse pr.rew. thanks
Sir, Are you using mach3 spindle control under "closed loop" ? Does mach3 PID work well in ensuring the spindle speed is kept constant under cuts ?
Mach3 uses spindle speed averaging it works well but can slow under a load.
@@CNC4XR7 thank you
My mach3 on the lathe does not cut the thread. stands on cycle G76 and does not want to cut the thread. please tell me where to dig? thanks.
make sure you have Spindle speed averaging checked.

@@dargindarginec9561 SSA should be checked. you do have a tach signal correct?
There is also a earlier video I did on threading please check it out.
@@CNC4XR7 Yes, the signal that goes to the index shows how many revolutions it rotates, I'll try to find this video on your channel. thanks.
@@CNC4XR7 Hello. I didn’t find your video you are talking about, can you drop the link?

what is the voltage of the signal your sending to the bob?

@@kclaptraffic Mach3 will only accept 1 pulse per revolution. send me a email with some pics of your setup maybe I can offer some advice.
I'm going to try a couple things this afternoon and if I dont figure it out I surely will! Thanks in advance!
i like your channel
Thank you!
