HPGL pen
Christer Johansson
Hi Art!
I am sometimes using Mach2 for creating PCB (Routing tracks and drill). I use a software that output the drill and mill data in HPGL. The HPGL data have pen settings (SP) for different drill sizes, but after the conversion i cant find any tool change data (M6) in the G-code. Do i missing something here?, or is this something you could consider to add in the HPGL import in the future?? Best regards Christer ===== PU; SP1; PA0,0; PA1930,406;PD; PA1930,406;PU; PA2032,406;PD; ===== |

Arts definition seems perfectly clear to me. The Index slot is the slot that will be unique, that's what makes it an index.. Garry To: mach1mach2cnc@...

Serious Tool offset/M30 problem
Steve Blackmore
Hi Art - there is a really nasty bug that crept in somewhere.
On a M30 the file rewinds and the tool offsets get removed even though nothing is ticked in logic apart from turn off all outputs. I haven't noticed it before because I normally change back to tool 1 which has no offsets, but I finished a file with tool that has offsets of Z 1.092 and X 10.7 - on M30 file rewinds and tries to go to X-10.7 Z-1.092 and stuffs the tool into the job!! -- Steve Blackmore |

Jeff:
sounds great and appears to run fine.(Sounds just like 3.5e)If I check both plasma and no angular discrimination, everything No downside to that. The idea is to match the machine to the CV best for it, so if your machine likes that mode, great. Thanks, Art www.artofcnc.ca ----- Original Message ----- |

Art,
Putting a G04P0 before each circular move just aggravated problem - much louder longer clunk. Plasma was not checked on logic page. If I check both plasma and no angular discrimination, everything sounds great and appears to run fine.(Sounds just like 3.5e) Is there a down side to running this way? Jeff E. p.s. I think you have a typo in discrimination - not des:) --- In mach1mach2cnc@..., Art <fenerty@a...> wrote: Hi Jeff:before each helical or circular move as a test. Is it now smooth??Plasma CV mode... |

if encoders are going to be used, all thatSo another way of looking at it is to think all that phaffing about with discs and holes and opto sensors and interface and then trying to oil/water proof it is unnecessary if you just fit an encoder. You can pick an encoder up for less than a branded toolholder, so why not do the job properly?. Possibly have an option for 'Encoder' to bypass the width counting? 'Properly' in my book would also make most of turning synchronous to and slaved off a high count encoder. Most operations such as turning, boring and threading are measured in mm/rev, and even facing is indirectly related so surely this way would be easier? Richard |

Re: Mach2 V4 threading :)
Art
Hi:
Well, here's a psudo-code algorithm that actually figures out if this is an index pulse.. 1) Found input is active, measure width of slot 2) Is ( this slot width - last width )greater than the (previous slot width / 2) 3) If so, this is an index slot.. 4) Repeat.. So 2mm, 2mm, 2mm, 1mm will work with the first 2mm becoming the index pulse in one direction whille the 3'rd 2mm will become index in the other direction... OR 2mm, 2mm, 2mm, 3mm will work with the 3mm being the index pulse in both directions. Note: I would make it a bit larger than 50% of the previous for stabilities sake. Say 2mm, 2mm, 2mm, 4mm as a rule... Art www.artofcnc.ca |

wrote: I'm not keen on "reflective" types. The oil and coolant flying around tends to make the tapes or shiny surfaces dull after a time affecting the operation. I got a load of slotted and reflective types off ebay very cheap. I'm using them as limit/home switches too. The slotted ones are impervious to coolant, but the reflective ones get confused when either the sensor or the reflector get soaked in coolant/oil. The flag or rotating disc clears any coolant or swarf away. No matter what type you use, try and build a cover or put them out of the way of oil or coolant as best as you can. -- Steve Blackmore Hi Steve, I'm heeding your advice. Hopefully the sensor will be mounted inside the "bell" of the pully for the spindle which is enclosed along with the drive train mechanism. Thanks much! John |

Re: Mach2 V4 threading :)

Heres an idea ...
why not use the same technique as used on nearly ALL car ignition pickups on modern software-driven ignition systems .. typically you have a say, 30 tooth wheel and a pickup .. and for the index mark, simply a missing tooth. thsi saves all the problems with spacing the extra-wide indes pulse in your scheme ( you havent explained whther this extra-wide slot should start in the same place as a normal slot or be centered etc this leaves room for error) ... a series of equally spaced slots with a missing slot for the index is much to describe and less prone to intepretation by the users in odd ways ... -- RapidCut CNC Technology CNC Plasma Cutter |

spindle sensor orientation
...just a small teeny question that save testing time when
mounting....a direction to a picture at some site would help Given the elongated rectangular shape of the sensor(reflective), How might it be mounted in relation to the tape on the rotating part.... would it(the sensor) be mounted with its "wide" head parallel to the tape strip or perpendicular to the tape? Whew!...details.. Thanks, John |

Re: Rutex tune a no-go on my machine
Art
Derek:
I think you just have an older board. The newer firmware has new register address's so is quite different from the old. Both versions work fine as servo drivers, it wouldn't be worth your ( or Vlads ) time to upgrade them simply to run the tuning program, but as time goes by, more and more will be able to tune this way. The firmware is not flash upgradable but requires re-soldering some chips, so its a case of luck at this point. Thanks, Art www.artofcnc.ca |
