[02:26:47] <rue_house> they all work like that
[02:26:57] <rue_house> little groove in the roller with some ripples
[02:27:16] <rue_house> if its slipping, its either cause its not tight enough or the wire is caught on something
[10:16:58] <jymmm> rue_bed: The newest HF welder has knurled feed rollers, this older one I borrowed fro the neighbor does not.
[15:28:16] <rue_house> does it have any bumps on the groove?
[16:24:14] <jymmm> rue_bed: bald and smooth as a baby's bottom!

[21:44:23] <Tom_L> http://linuxcnc.org/docs/2.7/html/gcode/g-code.html#gcode:g92
[21:44:35] <Tom_L> i don't use G92
[21:45:34] <Tom_L> the G54-59 work offsets are typically stored either in a file or in the machine's nv-ram
[21:45:46] <Tom_L> http://linuxcnc.org/docs/2.7/html/gcode/g-code.html#gcode:g54-g59.3
[21:46:13] <Tom_L> the 52xx numbers listed there are pretty much industry standard locations for those offset values

[21:49:26] <Tom_L> Page 13
[21:50:47] <Tom_L> if grbl implements this, they will have a place to store those values so when the gcode program calls a G54 it will look to those parameters for the coordinate system values
[21:51:57] <Tom_L> linuxcnc handles this as a menu option on the axis screen
[21:53:27] <Tom_L> linuxcnc stores them in a file
[21:56:52] <Tom_L> http://linuxcnc.org/docs/2.7/html/gcode/g-code.html#gcode:g10-l2
[21:57:03] <Tom_L> G10 L2 can be used to set the values directly
[21:58:32] <Tom_L> G10 L2 P1 X0 Y0 Z0 (clear offsets for X,Y & Z axes in coordinate system 1)
[21:58:53] <Tom_L> which is G54
[22:42:20] <rue_shop3> the key is G10
[22:42:32] <rue_shop3> that didn't come up in any of hte docs I was seeing
[22:42:49] <rue_shop3> it looks like G92, G10 and G54-59 are all a little possy
[22:43:32] <rue_shop3> I wonder what the L2 is
[22:43:38] <rue_shop3> and P1
[22:43:53] <rue_shop3> oh, maybe the P1 is the G54, aka P2 is G55
[22:44:24] <rue_shop3> just taking apart machine #2 (of 4 now)
[22:46:13] <rue_shop3> Tom_L, what do you use for cooling?
