T2 Engraving / Connector type?
« on: November 14, 2019, 09:49:29 PM »
I've just taken delivery of a stepper motor for my rotary axis and it has arrived with bare wires.
Can anyone please tell me what the name of the connector is (as shown) that I need to connect it to the board?

Thanks.

I can either create a post processor to strip them out or make it an option to include them in the G-code generation, both would be simple enough. I actually prefer the latter as that was a workaround for some non-standard controllers and should really be handled in a post processor (which I didn't have at the time) so let me add this to my list of updates.

I'm interested in what else you need to add manually, perhaps I could automate that?
Am I able to access the post processor? I've customized PP's before when I was using Delcam PowerMill. Been looking through my drive and blowed if I can find the install directory, lol.  Maybe snow blindness or simply old age.

I always have the image open on the desktop purely for reference so I can monitor progress.

Hmm the pictures I'm posting look weird... I'll try when I get home.
Don't give up!

I have started doing white ceramic tiles using the Nicky Norton technique. Have you heard of it?  It's weird for some reason painting ceramic flat white generates a black permanent Mark which can't be scraped off.
That sounds intriguing. Be keen to see pics if you have any.

Thanks, I'll look it up.

The STM32 boards are available in a Nano footprint package for about $11US from Mouser. They are 3.3V but have worked OK for me. I have had a home brew firmware (ARM version not available when I started) running for about three years. I currently prefer the GRBL-1.1 on a NANO.
Do you have link, and does it list the features & specs?

I figured that would be the case and that my expectations were going beyond the intended purpose for a low cost product.

After reading all these posts about the laser firing on connection and having the same issue myself, I finally got around to fixing mine.
Had to buy minimum quantity of 10 resistors for 70c and now have 9 that will outlive me . . .  if anyone can ever find them again.
It's such a breath of fresh air to not have to remember to wait to power up until after connecting. I don't know how many times I've burnt a dot where i didn't want one.
FREE AT LAST!   :)

It's a pity the controller doesn't accommodate work coordinates (G54 . . . G59).
Do they support sub-programs, as in M98, M99 with O**** subs?

For primitive testing I think it is easier/safer to generate the GCODE by hand. Then you KNOW exactly what you are getting.
I find T2 generates reliable code that I have confidence with.
What I'm doing though is generating code through T2 which is easier for an irregular bitmap graphic and then appending some hand written code into the same program.
This is where I'm using the back plotter to verify positioning before hitting the "Go" button.
The attached pic shows the backplot with rapids coded as G01 Feeds.

Thanks Zax.
Unfortunately, because the rapids are "displayed" as feed moves they are are indistinguishable from other feed moves graphically. I then replace all of those with a G0 and omit the F. This satisfies the back plotter graphically and the code runs ok with the rapids moving faster than the feeds although I don't know "how fast" as it's not displayed anywhere. I'm certain it's not as fast as the 4000 in $110, $111.

My experience with G-Code has been that G0 is a rapid mode that uses the "machine's" maximum set feed rate and a block with G0 specified doesn't show a feed rate (F).
Is it possible to have rapid (G0) set to read $110, $111 thereby omitting the (F)?
I have a very useful piece of back-plot software that allows for some great editing of G-Code and has a function where it can colour the blocks based on the their code so it's easy to differentiate and select rapids v feeds.

I just engraved an image "through" a piece of toughened glass onto the bottom surface.
I just used a standard can of Flat Black from the auto store and sprayed the under-side.
