Machscreen Screen Designer / Edit Silver/blue Screen for lathes with Screen4

« on: August 27, 2018, 07:06:35 AM »

I am trying to add a Caxis DRO to the fabulous SilverBlue screen set, when i open it in screen4 I get the main page but am unable to click on the manual or automatic buttons to enter into those pages i get nothing.
I am hoping this does not mean the screen set is unable to be modified??

Any guidance would be appreciated.

Cheers

Show"N"Tell ( Your Machines) / AL54b (lathe) project from New Zealand

« on: November 07, 2010, 03:27:48 AM »

280mm X 750mm
1hp
12mm tool height
Headstock MT4
Tailstock MT2

So they say the best way to learn is to do. I and suspect most of you learn by puling something to bits and in the process of trying to put it back together add a few things here and there for kicks and giggles.

I managed to pick up this lathe on the cheap because a customer the supplier had puled the motor of it as a replacement for a customer, this suited me great as it was my intention to replace the standard 1hp 1ph (240v) motor with a 3ph motor and a vsd.

I brought this machine mostly because I really needed a lathe for general use in the shop, I love guns so brought it long (they do a 500mm version as well) with the intention of fitting barrels in her.

Picked up the lathe at 10am back home by 1pm had it in bits by 1:05pm

General Mach Discussion / Can Mach do this? Bar feed

« on: October 29, 2010, 06:12:42 AM »

Does anyone know how to get mach to do this?

I am building a bar feeder, I have a pneumatic clamp mounted on the end of a ball screw with a stepper (rear clamp), the ball screw is 800mm long, if i want the feeder to feed 400mm of bar i acivate the rear clamp (on) deactivate the main clamp (off) the dive the axis 400mm pushing the bar through when it reaches 400mm the main clamp engages, the rear clamp disengages and the stepper returns to home simple enough.

Now for you mach experts out there, what if i want 1000mm of bar? yes i can write soe code that runs 800mm through as a first cycle then an additional 200mm. What i am looking for it a real trick way of being able to enter the required length (1000mm) into a dedicated region on mach called bar length and have mach work out how many cycles it needs to run in order to achieve the desired length.

any help would be appreciated.

thx.

Mach3 and G-Rex / G100 + G320's Encoder or MPG wiring

« on: July 25, 2010, 12:45:03 AM »

So i have a Grex and a bunch of 320's and there working great, i have always wondered why the Grex has pins for 5v ChA ChB ChI and gnd.
I have my encoders wired directly into my 320's so am not using the ones on the Grex, maybe i should be?

So i read in the G100 setup guide that you can wire an MPG into these inputs (example in the book used A axis).

This got me thinking, if I loop my G320  ChA ChB ChI (currently going to the encoders) to the grex ChA ChB ChI on my X axis and the follow the guide for setting it up as an MPG, would this allow me to temporally disable my 320s giving me manual control of the hand wheels while still allowing me to utilize the DRO?

thanks
