General Mach Discussion / Re: z height
« on: October 01, 2015, 01:43:39 PM »
Well got fed up with it so re-installed mach and now seems to be working better. What I do is zero x y for the job, jog the tool down to the sensor till the led is lit, zero z, then type in 45mm in to the z dro and all works,  it's a right pain having to do this for eevry tool change but at least I can cut now.  Would love to get it working the way DSP did JUst press a button for auto z and tool height and the same for each tool change, tried some scripts but none of them seem to work too well,  will have to try that 2010 screen set, will that work with only 1 tool sensor.  I really would have thought that mach3 would have included a script for that as they have an auto tool height button but I suspect it is aimed at more experienced users who can erite scripts,  looks like I have something new to learn!!
Thanks for you help

Thanks

Might have to get that screenset, a one button press was all I did with the DSP system.  So easy.
Still can't work out even when I jog the z axis down to the  material and set z0 without the tool setter it still cuts air. driving me nuts lol

Yes I am setting z zero as top of block. gone back to the standard 1024 screen now. should that be 45 or -45 in the dro.  Also while going through configs etc I noticed that in the tool table TOOL 0 has all its settings to -5430138233750...  Mach3 wont let me edit or change them so is this some sort of internal measurement to MACH3?

I just tried jogging the z axis down until the tool was touching the top of the workpiece and setting zero that way without using the tool height setter. now if I move the axis and the press go to Z it moves correctly and positions it just where it should be,  the only thing is that when I run the job it cuts about 20mm above the work surface which I take it must be in the GCODE from the toolpath creation from Aspire.

HI Ron.

Probably better to check I am doing things correctly as MACH3 is a whole new learning experience, DSP was so easy as tool height and Z height was so easy. What I have been doing, after reading the manual, is jogging down to my tool height sensor until the light comes on in the diagnostics panel, then going to the offsets tab and putting the 45mm in to the DRO in the gauge height setting ( I see there are 2 gage height panels) in to the panel on the top left of the screen and then pressing set z button.  Am I possibly inputting my gauge height in the wrong DRO?

Thanks for your help

Alan

Yep tried that as well still cuts air,  I did notice that when I create toolpaths in my design software it shows the home start as x0,y0,z24 which it takes from the safe z height setting so maybe this is being added on somehow in MACH3. It wont let me set it to zero to find out though.  I have the Big-tex screenset but that only seems to be of use if you have two tool height sensors. Never thought getting something to cut would be that difficult ???

Hi all,  just changed from DSP to MACH3 and just trying to get everything to work, having real problems with z height and tool setting.  With the old DSP system It had my tool height sensor height as a known parameter and all i did was put in a tool,put the sensor on top of the workpiece,press a button, spindle jogged down to sensor and retracted slightly, the I press run and it did the cut, when tool change was required just repeated as before.  The way I have been trying to do it in MACH3 is jog down to sensor till digitise light comes on  in diagnostics panel, set Z to 0, then put my sensor height (45mm) in the gauge height DRO and press the set Z button but when I run the job the cutter starts cutting air at the height of the sensor.  I must be doing something stupid.
If I use the old trick of a piece of paper on top of the job and jog down to where it is just pinched by the tool and Zero Z then it works ok. Could someone point me in the right direction please.
