Z losing Step going down

[bullseye]

What are you guys running as far as Rapids on Z...

I set it at 80 as syil suggested and then lower it in Mach to 20% and still lose steps only going down. all in the air..........rapid up is fine

What is the best setting you guys have found........

Thanks

I had a similar problem today on my router the z axis was drifting down. i figured out that my parrellel interface card (cnc4pc c-1) didnt have enough amperage going to it
i replaced the power supply with a TRUE 5v 1amp wallwart and it worked fine after that
i also changed my step and dir pulse to 5

hope this can help, good luck!

Thanks ....I think I just need to tune the Z stepper motor, when I feed it down its fine......

im using 45000 hz ...will drop it to 35000 and try it

80 isn't recommended on the Z. Velocity is default at 55 on the Z 80 on X and Y. Sounds like your acceleration is too high.

OK .. Thanks alot

I will get it tuned up today.......

Thanks that fixed it.......

Great to hear. The machine is very reliable and very accurate when you set the motors to the correct numbers. With setting the velocity and acceleration too high it pushing the motors beyond what they can do and misses steps. That makes for poor accuracy. Have a great time making chips!
