It is a Mach2 post processor but I thought it still should work.

The RhinoCAM post processor always gives me a G43 in the setup code but the control doesn't understand it (Mach3 1.84.001). Is the post wrong?

General Mach Discussion / Card Edge Connector Breakout Board

« on: August 04, 2006, 04:36:47 PM »

Has anyone seen a breakout board for a 20 pin .1 width edge connector? I could actually use more than 20 pin if that's all I could find. This is related to Mach since I am trying to connect Mach to an unknown driver through the card edge connector. :-)

General Mach Discussion / Re: High helix end mill keep gouging

These are good american made end mills. I found the error though. Thanks to all for the help. I took your advice of slowing the rpms and climb milling and a long ramp up and it did help, but I found the flexing was in the gantry itself (good call Graham). After a base plate replacement, both mills are performing well. The mini mill head still makes me take .005 at a pass at 10 ipm. Does roughing end mills speed up the process much? What other tooling have you mini mill guys used to speed up "hogging" large amounts of aluminum?

I'm pretty sure it's not the head moving. This is a moving gantry type mill. The x axis is a double nut thomson ballscrew and the y axis is a brand new daedal slide. I tested for backlash to .001 and there is none. The workpiece is a flat piece of 6061 and the grabbing takes place at different portions of the circle at different depths. I have not taken the 45 degree carbide to the grabbing stage yet.

General Mach Discussion / High helix end mill keep gouging

I bought 2 new high helix, center cutting, 2 flute, HSS mills from Niagara (D201's) and both of them are grabbing the workpiece. This is a simple circle pocket with conventional milling. I'm down to shaving .002 per pass at 4 ipm! When I put in a 45 degree carbide from Niagara (A245) it doesn't grab until I get all the way up to .003 at 6 ipm. The head is rock solid until the plunge then it hops and ruins the z location (inexpensive servos). It is just a mini mill head but it is very tight and not moving under other circumstances. Anyone doing any better with different tooling?

What do you mean? Are you having the controller move a certain distance and then manually measuring the actual movement? What is the commanded movement? What were the actual measurements?
