Art, Is it possible to have vertically aligned text on buttons? It would be nice in some instances to be able to have vertically aligned text if a person needed a tall skinny button to make the screen look better. John Guenther 'Ye Olde Pen Maker' Sterling, Virginia

Art - Just tried dry running a file but it's stopping on the line before a G32 even though "use spindle feedback" is turned off? Makes life a bit difficult for checking code. -- Steve Blackmore

Hello All: I have implemented a major change in the Macro functionallity, so the next version has the Macro execution as a separate Windows thread (till now I thought it was..it wasn't). It means that code such as the following will function properly... N = Question ("Number of Holes") D= Question ("Diameter of hole pattern") Z = Question ("What it the hole Depth") A = Question ("Offset start angle") Q = Question ("Peck Depth") R = Question ("Rapid Plane") F = Question ("Feed Rate") Nc = 1 PI = 3.1415926535898 A = (A*PI)/180 An = 2*PI/N Y = (D/2)*Sin (A) X = (D/2)*Cos (A) Do While IsMoving Wend Code ("G91") Code ("G00 X"&X&"Y"&Y) Code ("G90") Code ("G83 Z"&Z&"Q"&Q&"R"&R&"F" &F) Code ("G80") Y = ((D/2)*Sin (A+An*N)) - Y X = ((D/2)*Cos (A+An*N)) - X Nc = Nc+1 Loop While N >= Nc (This is a users code, it is flawed (Sorry Brian) by the fact that entering a zero strt angle will not do anything. A bit of work is needed on the math, but you get the idea. A script like this would peck drill a series of holes in a manifold configuration.) This change is important in that it means the engine is still running while the script is running. It will make it much more versatile in its use. When a macro is encountered, the currently running program is suspended while the macro executes. Any commands send via the macro script to the engine are interpreted and run as they go in. When the macro exits, the running program continues... This is in preperation for more complex wizardry functions. Sorry for any bugs encountered, or for any scripts it affects, but it should cure many ill's as well. You can see the new command IsMoving in use in the example. This function when used in the way it is above: Do While IsMoving Wend will stop the script from adding anything more to the queue until the previous code has finished execution. While not necessary, it will be necessary to make sure you do not overflow the 1000 commands or so you can put in to be executed. The Do/While statement will keep the buffer from filling until it is empty. Used stategically, it is a valuable tool to make a macro more stable. This combined with the new Portin Portout macro's make it possible to control fairly complex tool changers and external devices from a second port or IO card. With this change a macro COULD take control forever and do a continuous movement that lasts for hours before ending and passing control back to Mach2. Or, in the case of a toolchanger, it can start movment, wait for the appropriate feedback from external devices and then continue the program. (For those Macro heads emailing me lately, let me know if you need more....) Just a heads up. I can't release yet as I find myself in a spurt of post-vacation productivity. Probably this weekend or earlier... Art www.artofcnc.ca

Hi I suspect that a bug has crept into Mach2 RC 7 (I know not when). If you set up a Tool or Fixture on Tables screen and click the relevant button to save/make it persistent then you get the dialog box with already saved tools/fixtures but the entry for the tool/fixture defined in the DROs is not loaded with data and so is not easy to save. You have to type values into dialog to save them. At one time the values were put in the dialog grid from the Tables screen DROs. Best wishes John Prentice

Art Just a small one,When using software limits and they are activated,if you hit the limit the status shows this but when moving off the message is left on the status line or error line at the bottom of screen.Also what happened to the box in the logic screen that enabled you to input a figure for the machine to move off limit switches so the machine did not sit on the switch or is this now the debounce box?. Mark

Yeah, I know, you never got to see 8.0 and 9.0, they went away never got time to release them. New Features and Bugs fixed: 1) DXF layer is improved, plunge rates added. 2) DXF stutter problem gone. (Multiple lines generated) 3) DXF Spindle speed per layer and empty layer removal. 4) DXF improved optimization 5) Macro's changed to multi-threading design. They now run in parallel to the engine. 6) New Macro Commands: IsMoving Returns a 1 if the interpreter is processing movement. GetPortByte( address ) returns the byte at that port address PutPortByte( address, byte ) puts the byte into that port. 7) Dwell Bug checked and repaired. 8) OverRide input pin is repaired 9) When in ToolChange, Estop will stop that state 10) G28.1 repaired. It is now repeatable in its operation. G28.1 X1 will move rapid to 1, then home to switch ,move off switch and stop. 11) Flood Mist setting repaired 12) M30 offset removal bug. Only X was being removed when commanded by Ancillary logic setting. I have left RC2 as the most stable version until this is tested, particularly the macro control. If all goes well, RC2 will be removed after the next release. I still have some bugs on the list, but wanted to get this general maintenance release out. (Its been almost a month.) Thanks, Art www.artofcnc.ca

Art, I pulled Mach2 RC10 down and tried to install it. When it came up it said wrong driver version, so I attempted to remove and re-install the non apic driver. It keeps trying to install the Mach2.sys drive which does not work on my machine, and when I try to install the special driver it only wants to install Mach2.sys, not Mach1.sys. What do I do to correct this problem? I have tried to follow the instructions in the manual beginning on page 15 but it is not working with RC10. John Guenther 'Ye Olde Pen Maker' Sterling, Virginia

Spindle & coolant do not appear to work from within gcode Type G0 X10 Z10 M4 M8 G0 X0 Z0 M5 M9 in MDI and they work, spinle enables at correct speed and turns on & off, as does coolant Copy the above into a text file load as Gcode and run, X & Z axis moves but spindle and coolant pins are not enabled although diags flashing leds saying they are?? -- Steve Blackmore

Hi art my x y anz axis jog keys have a large delay when I load in Gcode.I push the key and it takes a moment for it to engage and when it does it moves quite a distance after I let up. this was happening on rc7 and now 10. derek

Hi Art I installed mach2 rc10 and the special driver and it changed all of my settings back to default. is this normal and if so you need to have a warning pop up telling people to backup their profile. Well I'm off to setup all my info..... ARGHHHH. Derek

Art, I have tried several times to install this driver with RC10, I even went back and completely reinstalled a fresh copy of Windows 2000 and I still get the blue screen of death when I try to run the driver test or Mach2. I had this working with RC7.1 but RC10 complained about using the wrong driver so I thought I would remove and reinstall it. Well, that did not work for me so I have now reloaded Windows 2000 and it still does not work. What have I done wrong? I believe I have followed the instructions in the manual exactly but I must be doing something wrong. Any help from you or anyone else will be deeply appreciated.

Hi All, After finishing my ball screw project and building a new adjustable mount for my spindle index sensor, I thought I'd try cutting a thread. I wasn't super happy until I compared it to a comercial 1/4- 20 bolt. I think the Mach2 threads look better! I used an HSS bit with essentially no radius, 300 RPM, coolant flowing, light cuts, and I think 30 passes. The caption says "first thread" but it was really my third attemp. The first two times I tried Carbide bits and both times snapped the end off, a small but fatal piece. I think I'll modify the G-code to step over the right amount so that I'm only cutting on one side of the thread. The stepover now is 40% of the infeed, which is a guess, (need to get out a trig book, high school was 50 years ago). The variation or errant rpm readings I was having were caused by a couple shiny spots on my pulley. Pulling the sensor back cured that until I get some flat black at it. Jerry

Hi, Somehow I'm missing the usefulness of all this touchoff stuff. Can you explain how it is different from just clicking in the DRO and entering the position you know you are in, ( Work Radis plus guage thickness)? Jerry offsets. Or at thick, type flash. Now >

They reset to zero no matter how I have the box checked unless I'm doing something wrong.

Hello List. I was thinking about trying Mach1 or Mach2 with my sherline mill. Im currently running TCNC with a 200Mhz pentium. I have a PII 350 in the garage I can use. I was wondering if I should get a faster PC or will the 350 be OK. Also, how do I know if I have a "Non Apic" motherboard? Will the software work Ok with out modifications to my zylotex driver? How can you set up a Joystick, and what is it used for, Jog? Thanks in advance for the help! Chris Seeley Just a note: I tried Mach1 / 2 and Master5 with my laptop when I first set stuff up. It would not work. I think it was due to the Laptops LPT port being part of the external docking station. (It's an IBM X20) So I used an old compaq with DOS and TCNC to get my feet wet. Should it have worked on this? If I can get it to work on this then that would be great. I tried several CNC progs, and non of them seem to work with it!! Just no motion!!

I had a post for mastercam9 ( I think it was a mill post from version 7 ) but I had a systemcrash and I hade to format c:\ Could someone mail it to me pls. It`ll be a great help. And if someone has a link for creating and editing posts ... would be great too. Thanks a lot. seagal.bennjamin@...

Hello all around! How can I automate tool length measurement? Is it possible via some script to send mashine to some position, where digitizing switch or metall contact plate located. Then lower Z until touch and read value to table. ?? Thanx in advance.

Hi: Is anyone else getting an Script Init Error when loading files in RC10? Just trying to track one of the nasty ones. I really want this multi-threading of the Macro's to work out, it seems the perfect way to do canned cycles. I will be able to create each canned cycle as a macro written in VB so changing Cycles and having wizards will be much easier. Thanks, Art www.artofcnc.ca

It surely can't be true that the eastcoast blackouts are caused by too many Mach2 users running at once? John Prentice :=)
