General Mach Discussion / machine not accurate

« on: November 23, 2011, 04:16:39 PM »

hi there i have a strange problem:

i did the "set steps per unit" process in the settings page of mach3 on x and y axes of my router. i did let the machine travel 50mm and measured it - it tells me 50.01 on the x and 50.02 on the y axis which is fine for me. problem is that when i draw a 40x40mm rectangle to be cut out in cut2D, export it as mach3 gcode and let it machine this the cut out part measures 39.56mm (x) and 39.73mm (y). i did try this with different speeds but the cut out piece is never near 40x40mm.

strange thing also is that when i change the steps per unit in the motor settings and then do the "steps per unit" process in the settings page of mach3 it still travels the right measurement. shouldnt it travel differently if i change the steps per unit in the motor settings?

of course i checked if my cutter is exactly 6mm (which is the cutter i have chosen in cut2d).

hmm, this is strange. it would be great if someone could send me some tips or ideas on what this f.... problem could be.

have a nice day out there!

Flash Screens / freezing

« on: November 10, 2011, 12:14:01 PM »

hi there,

i run mach3 on windows7 32bit. had problems with freezing computer. i am not absolutly sure yet but the freezing problem might come from the flash screen i designed. at the moment i run a clean mach3 install with the standard non-flash-screen and for hours the machine was working without a problem.

i do test the machine this way for one or two days more but in case it turns out that my flash screen causes the problem - has anyone an idea on how to solve the problem?

strange also is, that since i did clean install mach3, when i load my flash screen and then use one of the wizards (circular pocket,..) and then go back to the main screen of mach3 somehow parts of the non-flash-standard screenset and my flash-screenset are mixed up.

you lovely people out there help!

Mach3 under Vista / freezing newinstall of mach3

« on: November 10, 2011, 06:12:46 AM »

hi there,

i have some troubles which i hope you nice people out there can solve with me. i run mach3 under windos7 32bit. from time to time my computer freezes.

about my setup:

there are no background processes running - no antivirus, no network, no wireless,....
i did install the memoryoverride suggested for vista.

(1)
i deleted and unistalled mach3 from my machine including the mach3 pulse driver and did a reboot.
as i do not have a internetconnection on my cnc computer i did download the newest mach3 version on another computer. i did put it on a usb stick but when i try to install the new version on my cnc computer i get an error "a decompression error has occurred - file crc mismatch - data integrity error". i do not know what to do about this.

meanwhile i installed an older version of mach3 (which came with the controlboard). this installed ok.

(2)
my controllboard (TB6560) manual tells me to set mach3 on 35000hz what i did set. the driver test shows me 25000hz. am i missing something or is this ok. set this way driver test tells me that mach3 is under control and the performance is excellent - a nice line with very few very small spikes.

i read through the forum about the freezing topic and did all the suggested i have my parallelport set in the bios to bidirectional (EPP), i did uncheck "load startup items" in msconfig, did the vista patch and am running a clean windows7 32bit. it would be really great if somebody can help as i really want my machine reliable in working without me standing next to it.

have a nice day!
