General Mach Discussion / Re: A axis as extruder

« on: August 03, 2013, 11:21:56 PM »

Yes, thanks, it sounds right. But I don´t want to edit 10.000 lines of Gcode :-)

Is there a check box somewhere that can change it?

I´m using software called Slic3r ( Slicer), which is made for reprap, so I guess the generated Gcode is ok.

General Mach Discussion / A axis as extruder

« on: August 03, 2013, 04:08:00 PM »

Hello

I started my journey with reprap and Mach3 and I have 2 big problems.
This is one of them.

I use A axis as an extruder, which is pushing the filament down through a nozzle, but when it´s not printing it is supposed to retract / pull back the filament very fast, so it doesn´t drip and leaves strings through the printed part. Unfortunately it does.
I noticed that it´s retracting as long as the X and Y axis is traveling from one point to another. It should retract very fast before X and Y moves. 
You can see it on the video. Some fast retractions and a slow one at the end, time 0:24

Is there some settings that can change this behavior?
I´m getting arachnophobic when I look at some of my parts :-)

General Mach Discussion / Forgetting last tool position after restart

« on: August 02, 2012, 03:38:40 PM »

I got another PC for my cnc and Mach3 doesn't remember the last tool position when I start the software the next day. My old PC didn't do that.
Sometimes I'm forgetting to Zero the axis and when something goes wrong, like loosing steps, I loose my zero.
I can`t find anything about it in settings.

And is it normal that I can`t jog with 3 axis at the same time? Sometimes I can, but usually just 2. I did try with 2 different PCs.

General Mach Discussion / Re: Macros and dro numbers

I`ve found the answer in another thread. Instead of GetUserDro I typed the actual plate thickness and feedrate :-)

General Mach Discussion / Macros and dro numbers

« on: July 23, 2012, 11:35:35 AM »

Hello

I downloaded Z touch off plate macro and center finder macro and located them the right places with edit button script.
I was trying to type my plate thickness in the Offsets screen, but nothing is happening - plate thickness not set.
How can I see what number the dro`s are? I mean "GeetUserDRO (1151)" - how can I see which one it is on my screen? Maybe I'm trying to change plate thickness the wrong place.

And the center finder macro is moving very slow. It says FeedCurrent = GetOemDRO(818)  
Again here, I don't know where 818 DRO is and how to change the value.
I can see there is a little Feedrate window on MDI screen, FRO and F are set to 4 and that's the feed when centerfinder is active, but when I change the values to 10 and start Centerfinder, they are changing back to 4.

I don't know how to figure that out.

General Mach Discussion / Steppers not running smooth

« on: August 11, 2011, 07:18:52 AM »

Hello.

Im trying to change my way of milling and want to cut faster and not so deep.
But my motors are behaving strange when I try this. Specialy round objects and fillets.
Is it wrong settings, software, hardware, postprocessor or maybe just the limit of my steppers?

On the video Im changing the feedrate. Router starts to shake when it happens.

On the square cutting video, there are 4 bridges holding the part, so its cheating a little.

General Mach Discussion / Re: Z axis can`t Autozero the DRO

Thank you.
Right. Its not a standard screeenset. But the only one I could find with working edge and center finding macros.
Is there another options available?

I`ve found it:-)

The Gage Block High was set to +269.

This "set variable position" button is changing my touchoff plates thickness. I have try a few times. A bug?
