General Mach Discussion / Re: Code wrong?? Broken tool :(

« on: September 09, 2016, 03:10:36 PM »

Hi

If it helps I had the same problem with Mach 4 and fusion360

It's the z move in the g43 line

It should not be there so Mach support told me

The code should be
G43 H12
Z22.5




Its based on a tormach post with the root from a haas one

Stuart
Let me get on the iMac and I will post it

stupid forum software
change the .txt to .cps
put it in your personal post folder ( don't know where it is on windows )

General Mach Discussion / Re: Axis calibration precise but inconsistent

« on: September 08, 2016, 10:59:19 AM »

well that only account for a bit of lost motion

just a thought ( you know its a dangerous thing to do  ) try reducing the acceleration to see if it helps

on my small mill ( metric setup ) i use 100 acc with 4 mm pitch ball screws

just bored a 3 mm dia hole with a 2mm end mill just goes on a 3mm ground steel rod

What grade of precision are your ball screws , are they double nut or single nut

sounds like it's the ball nuts ,
Are they fixed tight , has the screws got any end float in them

All the about will cause the symptoms you describe

Have fun

General Mach Discussion / Re: Mach3 logic help

Lopata

To get that kind of accuracy none of the controller software you have mentioned will do it

Mach 3 or 4 are budget end and Linux CNC is a freeby

You will need to spend some big bucks to get that degree of accuracy you desire
Is your Machine rigid enough to take the g forces that your acceleration of the machine mass is subjecting it to?

What happens if you put a 0.0001 dti on the spindle to work piece and push on the gantry with o out 100 pounds force?

IMHO the controller software that you or using is not up to it
And remember no part is ever 'perfect' there will be some tolerance variation ,it's if that is within your expectation

Stuart

Sorry to down play Mach software but mach4 works for me and will hold the tolerances for my parts repeatedly over tens of runs.

Mach4 General Discussion / Re: Need setup help for smoothstepper and C25S BOB

« on: August 29, 2016, 03:15:14 PM »

Are we talking about the same thing I am not referring to any mach4 screen but the ESS setup screen , if I have the wrong end of the stick then I am sorry

From reading your posts I assumed yo needed help I configuring the ESS C25x combo maybe I was wrong

As I said I have just done a 4 axis mill conversion from a Far East board no wiring diagram and all wires the same colour this included 9 limit switches it was simple to do from the info fron DTG and Warp9 and From the c25x manual

I will leave it to other my 70year old brain cell is tired

Because the ESS has three

Not sure what you mean the screens are different to me the screens for the configure of the plugin are the same in 184 and 186

Now do not take this the wrong way but you are going to the plugin configure .flyout ESS , you do NOT  use the Mach configure screen if you do it will screw up the plugin

The first screen you see is an instruction screen on how to proceed if you do not see this you are in the wrong place

The info you require is on the Warp9 site

It's the one for the new 186 and it states that on the software screen it works because I have just done it

Have a look at DTG vidieo for the new beta plugin it's 99% of the 186 he explains it well

It's all there in the two places you just need to take your time and look and read till you understand , I cannot help you more nor can others as we do not have your machine to refer to , we do not know how you have it wired e.g. Pin outs , nor do we know if your setup needs active highs or lows

The one bit of info I will give you that is not easily found is that the inputs to port two are inverted in respect to port one ,e.g. If it needs a high on one you need a low on port two due to there being only one logic gate on two nad two on one

Pleas have a look at the two sources I have recommended they will help , when you sort it out yourself you will understand how it works this will help in the future

Regards Stuart

Ps they are nearly identical it's only under the hood changes

Thanks for the reply I will get on to Fusion 360 Team for a post mod


Thanks again

Mach4 General Discussion / how do i mod the m6 script to issue a m5

« on: August 17, 2016, 06:00:50 AM »

as above

my setup does all the correct things for a tool change box comes up ( i have not cancelled this yet ) led flashes with request to press cycle start

OK it all works H offset is correctly applied

what line of script do i put into the Lua m6 command to stop the spindle to allow the tool change


i get round this by stopping the spindle with the button on the right

Thanks in advance

Mach4 General Discussion / Re: Pokeys57CNC and probing

« on: July 24, 2016, 11:52:31 AM »

Mongoose

Well I do not use the same motion controller as you but the common thing is 3124 Mach ( note I use a ESS with C25 )

I have exactly the same problems the probing Mach4 tab is so flaky its unreal tried to calibrate the probe in Z it did its bob about then drove the probe though a piece of 12 mm MDF I was using ( because I don't trust it ) the probe survived

Some times it goes up to find the surface sometimes down , I have put this down to the probe being to high

The other oddity is that no matter what tool number I have assigned to the probe it uses offset 101

The touch module that you have trouble with is better the TLO touch off is OK measurement is , I don't know what its measuring , there is nowhere in both probing section to input the gauge line lenght of the probe

OK before I am shot down I do Know its a DEV build and is not meant to be used in anger but surly any feed back the team ( or one man ) gets is useful

One last gripe can Newfangled software please keep the manual in step with the current build and screen sets , a brief change log for the dev builds would be great

Sorry for the none constructive post

But that probing screen set has been around for a while it should work or at least give us the paying customers a manual on how to use it , you never know it may well work if used correctly
