General Mach Discussion / Re: Help controlling a stepper motor as a lowRPM spindle

May want to try it this way to see IF it makes a difference


ActivateSignal (OUTPUT7)
While Ismoving()
Wend
SystemWaitFor (INPUT1)
DeactivateSignal (OUTPUT7)
While Ismoving()

Have yall thought about fixing the screw rigid and making the nut to spin? Would give you plenty of room under the Y axis plate and put the nut out the back side.

I personally think it is about time you gave EMC a whirl (;-) IF you think it is SO EASY. You have not seen complicated yet(;-) Mach3 is about as easy as it gets in the DIY CNC world .  IF you cannot handle the Mach3 learning curve maybe it is time for Golf or maybe fishing.

There IS a test program supplied WITH mach3 and has been there for years. The RoadRunner file.

Obvious you have NOT figured out yet that THIS SITE is an ALL volunteer site and is NOT manned by paid MACH3 workers. But just people that have taken the time to learn it the hard way and are willing to help those that are willing to help themselves.

To adjust the toolpoint on center you always have the Y axis available to adjust it.

YES that clears up some of the mystery.

Will this thing make coffee in the morning as well(;-).

Have you considered just adding the turret mechanism to the spindle housing and just index the spindle then relock the turret solid each tool change. You could add the index slots to the spindle housing then use the Power draw bar to lift the turret off the slots then use the spindle motor to rotate the turret then release the power draw bar to engage the slots again to lock it down.

That way you do not need a huge servo OR brake mechanism JUST to hold the turret in position

When NOT in lathe mode the spindle then uses a standard BT30/40 tool holder.  IF you are going to move up to 40 you might want to consider Cat40 as they are more common in the used market than BTs.

G-Code, CAD, and CAM discussions / Re: Increment Spindle RPM per Cut

« on: September 09, 2012, 11:35:48 AM »

YOu can also use parametric programing to do a sub program and increment the Svalue each pass of the sub.

#1=  100   (100RPM)
G0 X0Y0Z0

M98 P1 L9
M30
o1
S#1
G1 X.010
G1 Z10
G0X0
G0Z0
#1=[#1+10]  (100+10=110 RPM)
M99

Maybe program a leadout arc same radius as circle that also raises the Z to clear part BEFORE it raises Z to Rapid height to move.

OR possibly retract the Z with a G1 move instead of G0 ?

AH ok so what you really wanted was a 40 series spindle size. Now I understand. SHould be plenty of used 40 series spindle assy out there that just need a rebuild.

HIYA Steve I don't know how you are going to compare price wise but this is about what you are building.
