General Mach Discussion / Re: Quick question
« on: March 04, 2018, 08:26:20 AM »
Thanks Tweakie, thats what i have been attempting but it makes no difference what value I put in the CW or CCW box. I  now have 20 in both boxes and it does the same thing as if I have 1. Could it be another setting somewhere?

Can someone please refresh my memory and tell me how to delay axis movement to let my spindle get up to RPM before it enters the cut.

Ok I ran the same file with the spindle of for about an hour then rechecked the z. It raised about 1/8". Any suggestions guys? The Z seems tight. Setting?

Thank you for the replies. I'm going to do a test air cut today to help with the diagnostic process. My tooling is new and and the Z axis is well lubed. It's ball screw. Very tight and no noises or play. If it's not loosing sets i'm going to start leaning toward settings. It's awfully consistent so I'm starting to lean that way.

General Mach Discussion / Loosing steps on the Z?
« on: August 24, 2017, 10:56:48 AM »
Hi guys. I have just bought a new to me Chinese machine stepping up from a Shopbot and have been cutting with it for some time now with no issues. Just 2D stuff. Recently I've been giving my hand a try to make a carved door for my house from 3d model I made from a grayscale modeled in Aspire. It's a very large file and is 4 passes roughing. I've noticed that the Z is rising over the with of the 30"model about 1/4 to 3/8 of an inch. I've ruled out the obvious things like hold down, collet slipping and software.  Everything looks as it should in the preview. I'm down to thinking I'm just loosing steps. I'm not very skilled on Mach as of yet but I did notice the Kernel rate is set as it's highest setting. Should the 4 GB computer computer that came with the machine already configured be able to handle that speed without loosing steps. I know nothing about tuning motors and am a little hesitant on doing it since I really can't deal with the down time right now, but is is what it is at this point.  Thanks in advance
