General Mach Discussion / Mach3 going off course of cut

« on: December 09, 2006, 01:07:25 AM »

I drew a little part in auto cad and then sent it to Lcam..Set it all up..Looked good when it displayed..Then sent it to Mach 3..It looks good in the display..Mach will be cutting just fine and then all of a sudden it goes wildly off course..you can see the proper blue lines before and then the yellow cut course in the display just goes wildly off course,and it goes crazy with the speeds too!! The router itself goes with this crazy line forgetting about limits for speed too...What is going on here??  Michael

No please, everything is cool here,really!!..I just didn't know what the rules of this where...That is sometimes a problem in forums..you don"t hear the tone that the message was written in..and you think that someone is upset or something..But I am not !!...Really!!.I am more than happy to pay for multiple copies and I will soon enough when I get the new machine running...I just didn't know...

All right then..at 53 inches per minute,when this table is designed around 30 inches,I am sure that the all thread would fling it self off the table and impale the ceiling!!!..   It  looks like that Mach is more than capable of this setting..I am headed for the "purchase section " right now...

Oh I don't mind the money at all...At the price set,I think for what the software can do,the price seems a bit low..This is what i have..one computer inside where all the design and try outs will take place,with no machine hooked to it...then I have one 3 axes mill outside to another computer ..when I design a part simulate here inside,I save the tap file to a disc and walk out to the shop and load and cut it...The plan is to get another computer and make another 3 axes mill,with more speeds and precision,but to also keep the old machine setup...I am honest to say when I say that if I need to buy another licence, I will..I was just wondering how it worked...Michael

I have seen posts of peoples machine where they have like 2000 or 3000 to move a unit...that might be millimeter though...At 25 mhz setting ,does that mean that Mach at its best spits out an impulse 25000 times per second?? ..It just seems that it is running at its max..I guess there is no problem with that ??

I was wondering about the licence restrictions..If I have multiple computers at my shop ( two running the demo mode right now and another inside where it is warm and comfy),do I need to buy three licences?? or can I copy the one licence to use in all three machines..??...Michael

General Mach Discussion / 28800 to move one inch

Hi everyone!..I built the David Steele large table using the Xylotek board and the 269 steppers,using the Mach three software..The control board came set at 1/8th step...the router table uses 18 thread to the inch all thread...if the math is right,and I am sure it is because it moves exactly one inch when you jog it, that takes 28800 impulses to move one inch...8microsteps X 200 steps to revolve one revolution and then X 18 to move one inch...8X200X18=28800...Doesn't that seem awfully high??..moving the pin to the 1/4 or 1/2 step would really cut down on that number..Do i loose anything like torque or speed by changing this?

Also when it comes to tuning the acceleration..I am not after super speed on this table..Making the axes acceleration slope a gradual one instead of straight up,doesn't that help with the accuracy of the table,not missing steps or possible going off course of the cuts??

Well...I had my first successful cut today...that rib...I went down the list and inserted the P.0625all the way down..12 times...because each hole was cut twice at two different depths,and then the outside profile twice...next is to try the D1 way..Can"t thank you guys enough..I am having fun again

To ger21..I do have ACAD 2000...it was' E'asy looking for it by the BAY if you know what I mean... ...because people upgrade all the time  but they hardly ever let go of things above 2002..If you let me know where I can find 2002 it would be much appreciated...Thank you also for the help...It was really getting frustrating there...Michael

Thank you Graham...I didn't know you could do that with the tool offset feature..I would like to be able to make a whole table of wing ribs on one tap file and having to scroll down the multi thousand line list would not be fun, putting in P.0625 at each G 42...Thanks again for your effort!..Ill let you know how it turns out..Michael
