General Mach Discussion / Re: Trying the 3d probing/digitizing function

« on: December 06, 2011, 07:05:03 AM »

Hi Ray,

You are not alone here, I get exactly the same thing with version R2.043.022.
The message box "previous sequence not yet complete" is just an error message from probing plugin code but I have to shutdown to clear it as well.

No help but lots of sympathy

General Mach Discussion / Re: Y-axis not moving

Hi Ben,

Your .xml file is in the Mach3 folder entitled Mach3Mill.xml or named after whatever profile you are running. Copy it, rename the copy to something like Bens.xml and post it. Hood can then check your Mach configuration and let's hope this is the problem 

It may, at this stage, be worth checking with a continuity tester / multimeter that your parallel port cable is good and that pin#1 is connected to pin#1, pin#2 to pin#2. etc etc. with no shorts between pins.

General Mach Discussion / Re: Home Switch Staying Active

Hi Jake,

It is more usual to have the switches wired in ‘series’ but no worries (mine are wired in parallel and I always seem to do everything differently to everyone else).
The ‘pull-up’ resistors are already mounted on the C10 board so assuming your switches are ‘wired in parallel’ then the C10 jumper (X5) need to be set for ‘pull-up’ (2-3) and your switches need to be wired to their ‘normally open’ contacts and Mach configured for ‘active low’ on the switch input pin#. Your actual switches will connect between the relevant input pin# and GND.

Hope this explains it.

My advice would be not to add any additional capacitor at all.  

I hadn't really thought about this until I tried it but as far a bipolar stepper motors are concerned rotating an un-energised motor by hand has some magnetic resistance - drive the stepper beyond it's stall point and it is perfectly free to rotate by hand in either direction without any of the previously felt magnetic resistance.

General Mach Discussion / Re: X-Axis rotation

I probably don't understand your question but I regularly use a rotary (A) Axis mounted to rotate either the X Axis or the Y Axis depending on the raster scan of the work (left to right or top to bottom of the image).

Perhaps you need to provide more details of what you need to achieve.

Hi Dave,

I am not aware of anyone using these analogue type of sensors (they are usually binary) so you may be pioneering new ground here. Interesting devices nonetheless and I would be most interested in hearing how you proceed.

General Mach Discussion / Re: Question about possible mach 3 project machine?

« on: December 05, 2011, 07:48:13 AM »

Hi Suade907,

Not quite sure why you haven't had other reply's to your post but, in my opinion, yes Mach can handle a 2 axis machine and as many switches and motors as you need. There are limits to the number of inputs and outputs from one LPT port but a second port (depending on your PC) can usually always be added. There are also a number of external motion controller cards with extended input / output capability it is just a matter of determining your projected needs.

Just a note Guys,

Do not fit a large capacitor across the output of a switched mode power supply it affects the sense response.

Hi John,

Perhaps a look through the lazy cam manual http://www.machsupport.com/forum/index.php/topic,12078.0.html may be helpful (I seldom use lazy cam so am no expert here).

Jake,

You say that your switches are wired in parallel and set in Mach as active low. If that is the case then check your 5 volt pull-up resistor.
