Third party software and hardware support forums. / Mach3 setup with Shark Hardware

« on: April 17, 2015, 02:57:08 AM »

Hi I have a White 2 box Shark.
I have a four axis parallel driven board from Hobby cnc.

I am attempting to drive the shark using this board.

I hope this sidesteps the Nc Pod issues. 

Does anyone have setup screens for Mach3 and Shark hardware?

NC Pod / Re: shark cnc-mach3

« on: June 29, 2010, 02:14:02 AM »

I have a cnc shark which uses a NC pod.

I want to use it with mach3 and also basic control panel.

I run two different classes that use different software.

I see there is a usb driver for mach 3 called ncpod usb driver

I see there is a firmware installer (v2031) for mach 3.

Is it a matter of changing drivers to suit mach3 and basic control panel?

Or are there two firmware installers that are mutually exclusive?

Can I swap between firmware versions easily? If so how?

If I have two different pcs one with mach3 and drivers and the other with basic control ad drivers will that work?

Thanks Peter.

loaded ncpod driver latest from oemtech
loads ok and talks to shark cnc from mach3

loaded update nc pod firmware (2031)
ran updater.
Error code ncPOD not found.
How do I update the firmware?

Thanks Peter.

NC Pod / shark cnc-mach3

« on: June 18, 2010, 08:47:12 PM »

Gooday.
Trying to get mach3 to work with shark cnc.
I already have built a hobby cnc parallel machine that is working nicely.
I understand parallel port patching.
I am using a separate xp computer just for the nc pod/shark setup.
I have loaded ncpod driver and plugin formach 3.

They talk sort of.
It looks like x is y, y is x and z down is z up.  Im told 1600 steps per rev accel of 15. Any other setup details?
I cant seem to find a simple patch panel to swap step and direction that works with the pod.
I dont have a detailed table of step and direction and other patches for the ncpod/shark.
Does anyone have a set of screen dumps of setting up mach3 shark combo?

Any good threads on this?

Thanks Peter

General Mach Discussion / Re: Using Mach3 with Reprap extruder

« on: May 04, 2010, 02:22:06 AM »

Thanks for the replies so far.
Here is some g code from a reprap part.
The speed and flow rates are already worked out.
I just need to tell mach3 that E=B so it can drive the extruder stepper.
Can this be done?
Can I display x, y, z 4, and 5 in the control window?
Thanks

General Mach Discussion / Re: Using Mach3 with Reprap extruder

Gooday thanks for the reply.
Firstly I am trying to make reprap parts using mach3 with a custom made extruder.
I would like to use the extruder to make other parts later.
Reprap g code defines extruder and uses E as the feedrate. See the G code below.

I want to be able to download a reprap part g-code description and run it using mach 3 software.
I want to know how to patch E onto a functioning axis such as A, so I can control the extruder.
I want to be able to control temperature on the extruder using the G code shown below.

Thanks Peter

Will set a feedrate of 1500 mm/minute, then do the move described above accelerating to a feedrate of 3000 mm/minute as it does so. The extrusion will accelerate along with the X, Y movement so everything stays synchronized.

RepRap thus treats feedrate as simply another variable (like X, Y, Z, and E) to be linearly interpolated. This gives complete control over accelerations and decelerations in a way that ensures that everything moves together and the right volume of material is extruded at all points.
Example: M104 S190

Set the temperature of the current extruder to 190oC and return control to the host immediately (i.e. before that temperature has been reached by the extruder). See also M109.
M105

Example: M105

Request the temperature of the current extruder in degrees Celsius. The temperature is returned to the host computer.

General Mach Discussion / Using Mach3 with Reprap extruder

« on: May 02, 2010, 09:09:02 PM »

Gooday from Sydney.

I have recently built a four axis gantry robot running Mach3 software.
It uses a four motor parallel port hobby cnc controller, and runs on windows 2000.

I am building an extruder and want to know how to make parts with this rig.

I have four active stepper motor channels and motors working.

Mach3 can control up to six channels.

The real question is how do I assaign the b or c axis to driving the extruder?

Has anyone been down this path?

Thanks Peter.

General Mach Discussion / wizards and gcode

« on: April 27, 2010, 02:24:31 AM »

Gooday from sydney.
Have just installed mach 3 and written my first text to prove xyand z allwork.
It all worked fine.
Today my write files have acquired a series of tool path concentric circles.
These are strange and annoying.  Where did they come from, and how can i make them go away.
I wrote a new text wizard file and it also developed the circle virus.  Any Ideas.

Secondly I seem to have lost the grid of holes wizard.

It downloaded with mach3 late last year, and I cant find it on later downloads. Anyone know where it is?
Can I download it and other wizards?

Thanks Peter.
