TinyG Connection Issues page 2

Firstly let me thank you. You have obviously done a lot of homework on my account. I really appreciate it!
You certainly cleared up some confusion. I think through following a video in open build completely lost track of the facts that I had a tiny G and not arduino and was expecting my results to be the same as theirs. Big mistake! I have now deleted all the G RBL programs. After setting cool term and TGF X as per your instructions. I can now execute $$ and get a dump. Unfortunately I have never used dropbox, so I will have to check into that as well. For the last time I will put the dump here. Sorry about that.

The movements I was getting from the machine were quite erratic and almost throwing the machine off the table. I changed the velocity maximum and feed rate maximum from 16,000 to 1600 in both cases. The speed now seems reasonable to my untrained eye. The movement distances were also very far out so I used a ruler to set the distances. Unscientific but it worked. Hopefully tomorrow get the wooden base into the machine and should be able to do some useful testing.
I'm still having some trouble with TGF X in that I can't jog the individual motors.
I had a look at chilli pepper and J CNC but decided to leave those to look at in the future. I can't get TGF X to execute commands either, so I have quite a bit to learn as it is!

Hi Gwandad, I looked through your config and did not find anything unreasonable. I only noticed two minor things:

The "travel per revolution" for X and Y axes is configured as 53.34mm. If the parts list of the Ox is up to date, it should be 60mm (belt has a tooth every 3 mm, and the pulley has 20 teeth; 3 x 20 = 60mm per turn). Might want to recheck this, but your measurement is definitely more reliable than (possible outdated) theoretical values.

And I think it's good that you lowered max velocity, you might want to do the same for acceleration/jerk ($xjm etc). 5000 million seems a bit high to me, my Shapeoko runs at (very conservative) 80 million. Better start low and later test the limits when you have confidence in the machine.

I can't really help on tgfx, as I don't use it myself, but clicking on the bottom bar opens the console where you can type in commands and see the results.

I wish you mucho fun with your Ox!

Great joy & jubilation in the house. This afternoon I printed out the sign “SHAKEOKO 2” using a sharpie pen fixed to the z rail & executed the gcode from the Shakeoko tests.
Thank you both for your assistance. chmr, you got me out of the wilderness & in OZ I would owe you a beer, but given the distance I will drink a toast to you both, later this afternoon. I do hope you appreciate the effort I am putting in for you guys!!!

I've been out of action for quite a while, but am getting back into it now.I have made some nice things, but there is one remaining issue & that is the home switches. I can't get the TinyG to recognise them. I've gone though the Homing & Limits Github, & seem to have all the relevant settings. If I do a home on x for instance, it runs through the switch & rattles against the stop. If I set the Xmax to 300 (mm) & push the carriage to the far side, a home (28.2 X0) sends it back the 300mm OK, so it looks like a faulty switch, but it's not. All 3 switches are new & test OK wwith a multimeter. The Y & Z act in the same manner. Any suggestions, please?

Sorry for the delay.
Hopefully this will be the info you requested https://www.dropbox.com/sh/0se9hqhy19dsyfl/AADUz3xbkPQZv1DeK0YZl5Gta?dl=0
Yes I found out abouttgFX. Shame, I really liked it!
I'm using Chilipeppr, or learning anyhow.

Forgot to mention I followed https://www.synthetos.com/tinyg-homing-how-to/ through with no success.

Yes, the OX is belt driven & has 3 Nema23 & one Nema17.
I sent you the wrong file, I had been dropping a lot of values down to see if speed had any effecf, but I have to confess, I have absolutely NO idea where I got 1.25mm from! Of course it should be 60. I have put the current file in Dropbox as Dump2 Thanks.
Back to the problem, Ihave (Ithink) checked the dump with TinyG Configuration for Firmware Version 0.97 & it looks ok to my untrained eye. The switches have absolutely no effect. I have even changed the TinyG card! No Joy
I can use the machine OK without them, but I feel I should have them for safety if nothing else.

Sorry Mate, I've really made a mess of this. New link https://www.dropbox.com/s/a0e1byha72tau2l/%24%24Dump2.pdf?dl=0
Switches are actually NC.
I am using CP & have gone through Homing and Limits Description and Operation for TinyG several times. I disable Y & Z, use G28.2 X0. If the spindle is placed about halfway & the command is executed, spindle moves slightly to the right, then accellerates to the left & crashes into the stop & switch. If I move it to the far side it will stop when it reaches max & goes into it's expected latch/unlatch then stops OK. It just doesn't recognise the switch. Same if I do the same on Y.
I had reached this same impasse last year before I got ill & convinced myself that it was the card. With a new TinyG, exactly the same!

Thanks for your assistance.I'm sorry I wasn't more explicit with my descriptions.
I have done all those checks several times, but there is an old saying about checking your own work & making the same mistake twice. I think I'll try to find someone who can do the check for me. If it still fails after that, I'll start a new thread as you suggest.
