Tree 325 Delta 20 Tryiry to do 5 x 5 bolt pattern.Wrote program on delta 20.
N1{9} M6 E1 T1 S200 ,
N2 {9} M3,
N3 {0} X+9.5656 Y +6.3430 Z-1 F.5 G1 W.2
N4 {5} X+9.5656 Y+6.3430 Z-.5 A90 R2.5 G1 W.2 H05.05
N5 {9} M30
When i push cycle start it goes to home position,
then it goes to X 14.8605 Y13.6796 z never moves.
E fixture offset is set for center of bolt pattern
What am I doing Wrong

[laszlozoltan]

did you put a decimal point after the z-1 ?

[jdracing]

Yes

[laszlozoltan]

sorry; I did not mean to get your hopes up; I used to work on a tree a number of years ago so I looked at your post and noticed the g code you copied was missing that decimal point; I recall the gcode format was a bit off the normal fanuc- it was something kinda simple stupid I remember but I can't put my finger on it, so again my apologies I cannot help you

[jdracing]

Thanks, I'm sure its something simple.

Not fimilar with your control ,but have run and programed alot of different machines ...May want to start with a G80, G40 & so forth to clear any modal commands and get your G98 type comands in it to get in a clean start-up state ..

[jdracing]

Hi, thanks tried that. no help. question, wouldn't the G1 be the active modal code and cancel all others? I have Ellison manual thanks to elnerdo. And the original dynapath manual. I think your right I need to get the dynapath to a clean slate, How to erease it's brain and start over without hurting it?

Thats a quirk with the delta. Change your start (0) code to x0 y0. You must position to the center of the bolt circle first, not the starting hole.

[jdracing]

Thanks underthetire I Changed your start (0) code to x0 y0. and am positioned at the center of the bolt circle.when it gets to N4 {5} X+9.5656 Y+6.3430 Z-.5 A90 R2.5 G1 W.2 H05.05. the Z goes to minus travel limit, so I put in tm2 to restrict the Z, then X & Y go to no mans land X+21 Y+ 14 I don't understand what is going on

[underthetire]

You know, the h5.05 does not seem right. H5 would be correct for number of holes. You only needed the decimal for skipping holes.
Also, the (0) before the bolt circle should only contain x and y position,Centering on the bolt circle. nothing else. I just can't remember if the bolt circle is called out as a radial value or diameter. Seems like it was dia unless you put a / after the value.

I used to teach the Dynapath class, but it's been 15 years, so it's fuzzy to me now.

[jdracing]

Thanks again underthetire. I put h05 worked, r is radius, another question ? is there a way to slow the rapid travel down, when it rapid travels I get an X servo error. needs to be rebuilt, I pulled one of the brushes almost nothing left, Get by for a couple of small jobs.
Thanks to everyone thats helped me I really appreciate It

[underthetire]

If I remember right you can slow the rapids in the setup menu. It allows the feedrate override to control the rapids. Once you get used to the quirks, its a fun control. What motors on the Tree, MSI or Baldor? I still have my Tree file around somewhere, probably in the storage shop. There is a tuning procedure for the axis. I would remove the brushes and blow out the motor a little with compressed air. Don't go nuts with the air.

PS, stand clear when you do it, bunch of black dust will come out. Also, there are Zerk fittings for the axis bearings for X, throw a little white grease in there to help.

[jdracing]

I'll try that tonight Baldor motos Can a regular electric shop rebuild or would I need to send it somewhere Thanks

[underthetire]

You need to check the power leads to ground, to make sure they are not dead shorted. If they are, keep trying to blow them out with air. If you can get them clean, just put new brushes in. The encoders actually fail on those and get loose inside, causing erratic signals at rapid. The other problem is people don't get the drives tuned, so the gain settings could be off causing it as well. Last price for a motor repair I got was close to a new motor, but things change so I don't know any more. If you get to that point, I can ask the local Tree service guy I know where he gets them done at.

[jdracing]

Thanks I took all the brushes out blew it out, some black dust not a lot. 2 brushes look good 2 wore out, vibration in motor. your advice on how to slow rapids down worked great. Once I got all that done. Drilled the 5 x 5 Works good, Once I get used to this control I'll really like it. I'm sure I'll have more problems, but I'm getting a better understanding of it. Thank you very much

[underthetire]

Cool. You can get new brushes through a lot of places, one being McMaster Carr. I'm guessing once you get that solved you will need to tune the axis drives. Usually vibration in the motor is too high of gain.
