Hello all. Made some progress today with the Tree VMC. Had some fun, and manually made some chips. Decided to give a go with conversational programming and ran into a ditch, of sorts.
I can program tool, fixture, spindle, etc. - however - I cannot seem to select an event. What am I missing?
For example, N0002 and I want to (0) position, or (1) linear mill and so forth - how is the (event) entered? I assumed I would simply hit next event, then (0) for position - then load coordinates - but I can't seem to have it accept anything other than M codes at this point. What am I missing?
Well, you should be able to press "EVENT TYPE" then select 0-9 or C, E,M,P, R,S,or T. These are all event types. Once selected it should bring up the corresponding screen listing the data location that can be filled in for that event.
Other than that maybe I am missing part of your question. You can also check by using your text event to make sure the 0-9 keys are working.
Somedays I think I'm losing my mind. I could swear I've done the exact sequence above dozens of times and never made it to the input parameters step. Booted the mill and tried it just now - shazam - it works.
I have a Tree Journeyman 325 mill with the Dynapath Delta 20 controller. I've had the darn thing for almost a year now and am still trying to get it in service. The trouble is getting the CAM software with the appropriate post processor to work with the mill. I have several CNC machines using Mach3, but this one is very different.
What CAM software / post processors are you all using?
A slightly altered fanuc post will work (though there are a few stupid things).
For arc center the vector is absolute arc center.
Since the editor in the control is event driven, you cannot have two "G" commands in one line.
For example, if you rapid Z to position and the call G1 G41 X1.0, that would be incorrect. Not a problem because you probably would have had the Z move as a feed move anyway, just want to point that out.
As far as sequence numbers go, I increment by 1. If I have to insert a line at the control after N10, you could type N10.1
Hope this helps!
Also, I have another question. Am I correct in assuming that when no tool Tx has been selected and no fixure Ex has been selected, that the machine will move position relative to the 0 point set by MODE, 0, 9? I have some programs that seem to move in absolute coordinates instead of moving relative to this point.
Looks like the problem is on line 28 (D0).
Lets cut a 2.000 X 3.000 block with a .250 radius on each corner using a 3/8" EM.
X0Y0 is C/L of block, Z0 is top of block
3.000 is along X axis, 2.000 is along Y axis.
As far as fixture offsets, I've never used them. I do as you say and zero XY with "MODE,0,9". I've also not used the Z offset either yet, I just touch-off the tool and zero Z axis. I do use tool offset for cutter comp.
