General Mach Discussion / Re: Use of tools in a turret?
« on: February 27, 2012, 10:30:26 PM »
Rich we are way past me being confused! Eventually I will get some of it correctly. I do change the tools via MDI. Touch off tool 0? Or by touch off do you mean set my machine 0,0 to be my Tool 0's location? Then I notice you skipped tool 1, according to Hoods method, this was because all other tools vary from tool 1, correct? Tool 1 should have no offset in Z or X, correct? I like the straw idea, so would my tools! Up until this point I have been using a piece of stock .3115 in diameter, if when touching tool 2 to the X, shouldnt I have the diameter in the X part zero box upon pressing touch? Since I never touch tool 1 til the actual part is installed it baffles me how anything knows where it is.

Hood, It wouldnt have mattered on the screenset, I would have still done it wrong the first few times :-) SS seems to work fine for the people who really understand it. I have a few problems but i cant blame it on the SS, it just adds another variable tha I am not familiar wiith. Fortunately there are people like you who are willing to share their experiences and reassure the rest of us that products do work if set up and used correctly. With all of the weirdness going on in my set up, do you think I should do a fresh install of Mach? If I did, all I would really need to save would be my xml and tool change macro wouldnt it? NFS wizards maybe?

General Mach Discussion / Re: G28 in Turn causing problems?

BR549/Juniors Auto Sales, That makes sense as I do have my homing speed at about 75% of max. I would have thought the F# would have overridden the setting. At least now I know what is responsible for the choice of speeds. Still a few concerns, why does it home at different speeds seemingly dependent on which tool is selected? Also why does the toolchanger get affected only when a tool change or move was made prior to the G28?  Why does G28 with no other command cause motion? My understanding was that it shouldnt move without an axis being specified. Also since the homing speed is set on the homing/limits page, F wouldnt be necessary in the Gcode would it. So G28 Z0 X0 would be a viable command? Again thanks for your input.

Ditched every one I could find. I am having some weird things occur. Very erratic. Might have to dump it alll out and start fresh. I dont know to suspect the SS or Mach or Me (ok well I can blame me as I am sure I am part of the problem). Just baffled.

Ok now it really gets weird. I repeated the above after all M6End files were removed (unfortunately I didnt try it before), if I do complete the G28 as in G28 Z0 X0 F6 it will go home at a reasobly high speed disregarding the F speed. It also homed the X in the wrong direction on 1 tool but not another?

I diid some more testing. I come to find, I can home and move of axis then hit G28 alone and it returns to home (many times, 10 or more). However if I jog my tool changer or ask for a tool change thru MDI and then hit G28 it causes the toolchange stepper to back up (everytime). I am now removing any trace of M6End files on that particular computer as it will be used for a lathe only. Hood was suspicious it might be causing some issues.

Graham, I just went back, restarted my computer, replugged in my Smoothstepper and opened Mach. I homed my machine. I then jogged off of both Z & X axis a few inches. I then put "G28"not followed by any axis designation and pressed enter. The machine started to move in Z first and then in X (I wonder if this is due to an M6End file Hood was reffering to?). In my usual pressing of home, X retracts first and then Z. Oddly enough, the first 3 times I attempted a G28, it retracted as it should (or how I perceive it to work). Then on my 4th attempt the stepper for the tool changer was screamiing against the pawl. Quite odd. What do you think my next course mof action should be besides not using a G28?

Hood, Thanks for the review and tips. What is an M6End do? Is there any negative to getting rid of it? I have tried the tool setting quite a few times and get varied responses. Though I think I am following yours and Rich's tutorials (I have tried both ways and they may be the same?,but written or understood differently). I am still very puzzled as to why my axis go different speeds with different tools but the command is the same (G54 Z0 X0 F8). Also trying to do exactly what your instructions said one of my X axis offsets was in the 9" range! Not Z, X. My X limit is 4 or so. I was touching the diameter of a .3115 piece of stock. I tried it quite a few times attempting withand or without pressing enter, with or without pressing "part X or Z" and using only the touch button. I get seemingly odd and misunderstood behavior though I feel like I have read enough to at least get the 2nd tool to also touch my stock in the general area (I expect .001's but would be very happy within an inch or so in the beginning). Tool 1 always seems to behave correctly ;-)

Graham. Thanks for any advice you can impart as I am not well versed at all. I dont remember if I assigned an axis or not. I will have to repeat the procedure to verify. I do know that the A axis tool changer has no homing or limit switches so to hear it attempting to rotate against a pawl is suprising. Well maybe not suprising, not expected or intended. I inherited a tool change macro that seems to work well, though his machine might have been slightly different in regards the switches etc. Could the tool change macro include info for a G28 move? Should a G28 alone cause movement? Thanks

Maybe this time?
