Re: offsets
Spencer Chase
开云体育i am not quite understanding how the non 0 values get in to the G54 table. i start the machine and jog to the position that i want to be 0,0,0 and then zero each axis. if i look at the tables at this point there are seemingly arbitrary values in the G54 entry but i know they are not arbitrary and that they are used in the system.if i change all G52s in my gcode to G10 it makes sense that i can then edit the G54 values to add additional offsets but i still am not clear on the advantage of doing this. will i then be able to set the G54 to 0,0,0 plus any additional offsets i want to add besides the G10 ones that are in the gcode? i will give this a try but it would be helpful to know if this is really what i should do. i don't want to edit the gcode when i need to make a minor offset change. i want to be able to do it from the MDI or from a custom button that i write a script for so i need to make the additional offset persistent independent of what is in the gcode.

Re: offsets
Spencer Chase
开云体育likewise, i was very confused by offsets which is why i asked. i really like the programatic approach but it will require writing the scripts and changing every G0 and G1 line from my gcode. unless there is a really simple other solution (still need to check out the G10 approach) i will probably try this when i want a programming challenge.On 2/26/2015 7:20 AM,

Re: offsets
Spencer Chase
开云体育if i were using a script for the code, that makes sense but currently i am using just plain gcode. since i am a programmer (mainly perl and c) i do like the idea of doing it this way but i am not good with vbscript and will probably save this for another time. i could make a custom button that incremented the variables and moved the machine to verify that the offset was changed.once i use the machine for the first 1000 parts and see how often i really need to change the Y offset, i'll think about taking on this project.

Re: Dolphin Partsmaster Question?
开云体育I use Dolphin all the time, import DXF files all the time, and have never had a problem with the process.? I routinely use Autocad or DraftSite as the drawing package, then import the DXF into Dolphin, if you would like you can send me the File and I will attempt to do it on my system and report the results.? I would suspect the problem is perhaps Inkscape is not producing a usable DXF file.? Jonathan ? From: mach1mach2cnc@... [mailto:mach1mach2cnc@...]

Re: Mach4 - Axis Correction
开云体育I don't know if this has come back to the surface or not. I know it was started. Let me talk to Steve and see where he ended on that one and I will post back here.Thanks Brian On 2/26/2015 2:20 AM, Daniel

Re: offsets
Spencer, The values you see in the offset table is the distance from the local (G54) zero position to the machine zero position. When you reference/home the machine the master coordinate system is reset to 0. If the value in the offset table is 0 then the G54 coordinate system is?"right on top" of the machine coordinate system. If you move the machine to an arbitrary position and press the Zero X button then the distance from the machine to zero to this "new/local" zero position is recorded in the offset table for the currently selected coordinate system (G54, G55 etc. You can set offsets with the G10 command. I'd probably use that instead of G52 in your current setup and THEN use G52 to shift the thing further if that's really needed. Sounds like there's quite a risk of "getting lost". /Henrik. 26 februari 2015, Spencer Chase lists@... [mach1mach2cnc] skrev:

offsets
Spencer Chase
i have read everything i can find about offsets and still can not figure out exactly how to do what i want with minimal effor tand confusion.
i have a bunch of little gcode snippets that do the various features i need in my parts. i have them all centered around 0,0,0 and am using G52 offsets in the code to put them in the right place. this all works and i can adjust the relative position of them by changing the G52 before each snippet. i also want to be able to apply an offset for each part if needed. i can go to the offset tab and add or subtract from the G54 (default) offset. it always seems to have some values in it but i have no idea where these come from. if i want to add an additional y offset i can edit the y value and it all works correctly but i am not sure what i am doing. i need to know the easiest way to apply an additional offset for an axis or two or three with out having to remember the values in the G54 in the table, add or subtract from it and enter a new value. there must be an easy way to just add or subtract an additional global offset without editing the gcode. how might this be done? -- Best regards, Spencer Chase 67550-Bell Springs Rd.

Upgrading a Lathe with M4
Hi People,
Currently have a Wabeco lathe currently equipped with NCCAD software and the Wabeco “in house“ hardware for X, Z, the tool changer and infinitely variable speed control 0 ～ 6000 rpm. I understand that a lot of these machines have been converted in the US and other places to use a G540 Geckodrive and Mach software. Would like to do the same, I have been at this bag of bones for nearly a year on and off and still have not got on top of it. Keep remembering the set of the mill. Took a week to convert it and two days to master the concepts and Mach 3. Any hints at all on what to do and or how to do it would be most gratefully received. I have the G540 (2 weeks old) and a lot of other fruit to add but am still looking for tips please. All and every hint most welcome. Russell Dunn Ferlach Austria |

Oblong Holes
REX SMITH
I’m machining a plug panel that has assorted hole sizes for mounting plugs. Each of the holes that gets machined is eccentric (oblong). I thought at first that it was due to a backlash issue, but doesn’t seem to be the case. The holes are eccentric diagonally. If backlash, it seems they would be eccentric only in the x or y direction. This would indicate something in the software. Anyone seen this?
I’m running Mach 3/PMDX/Gecko/RF 45 rex |
