Hi Malri,

CVD Is a technic that i cannot use for cutting. Im just building my machine for genaral cutting. Just a hobby project. CVD is above my doing and also think you dont want to do that at home. And the equipement isnt available for me.

Greetings,

Christian

haha yeah i mean a separate machine for making stones to cut.

it's a project i wouldn't mind venturing eventually.

not enough funding yet thumbsup

Hi Thomas and Thomas and the rest smile

I Think i have found the solution for controlling multi axis at once, i hope to program this today. Have thougth about how to use multi axis and its all about factors so if i do the calculations for the most pulses at a single axis the speed is determent by the first calculation. So no need to calculate the other axis. This way you can get the perfect triangle for example by two axis. If you can make perfect triangles you can make everything. So it would not matter how your or where your point is it wil always be a triangle. A computer generated circle is build by using only triangles.

I also have rewrite my accelleration and deaccelleration table and i can use that for creating the best start/stop.

YES! Its also possible to generate parabolic facets! big_smile

Hoping now that it also going as well as on the microcontroller. If im correct it will work on all axis at once! So im verry happy! Hope its going to work as i have in my head. This means i need to program everything and test the beest tongue I can program it first on the pc but then i need to build my electronics cabinet.

Greets,

Christian

Hi folks,

Did some testing over the weekend and i think i need to take it as it is. Due to rounding the integers of the steps you'll get a loss in time and im not shure how to fix that because the arduino cannot handle in Nano Seconds... But im thinking im getting so verry close that i almost going to rewrite my program for the arduino and test it on the machine.

Here are the test results for starting the motor its not complete yet, its only starting the motor not yet stopping etc. As you can see i have a time difference 427uS between the two axis. This is caused by rounding the delay length. For the rest it should work.

Accel_Test_Multi_Axis.jpg

The red and blue lines presenting the steps of the motor. At the debug below are the test results. Im thinking that i will test this on a arduino and continue the build.

Christian

Edit:

I was thinking about executing the steps but i think i can scatter the time difference over the length of the pulses. Becourse the delay of the pulse is the length/speed of the motor. So mayby i can set the delay into the on time of the motor pulse. And the calculated time wil be as is for the delay time in the off time between the two pulses.

Uhm.... if i am correct the delay time between the pulses is causing the speed of the motor. But the delay time of the pulse does almost nothing (needs to be constand) But mayby i can use the loss time in the 'HIGH' moment of the puls.

Sorry that it is hard to understand this im thinking out loud tongue

The above is not going to work... Almost got it but not there yet. I need to use the red line as an example and do my calculation on that one. Hope its going to work. Sorry if im making it myself a bit hard but im better off at the end of the story! smile

Still having some problems but these can be ignored. For now i need to run each axis alone. So i will do that. The other problem im now facing is that my miller, my friend cannot mill at this time, he has some medical issues and needs to recover. So the only thing i can do is build a new CNC Router to complete the facetting machine. Its taking a lot longer than i hoped but we will continue!

New Video!

Hi There,

Soon verry soon i will do a new update for the machine by the way i tried yesterday one of the automatic toolchangers for the machine, have ordered an compressor, i hate those things always if i want to use those they are defect or broken lol. But the test did fine! Its a 4 liter Jun Air compressor 8-13 bar 33db, nice thingie but an oldie. It does its thing but still complaining about compressors tongue lol.

Here the test video:

Soon more, already started with the electronics!!! And found some one who wanted to help me for the cutting discs!

Greets,

Christian

Major update!

Didnt do much on the new cnc but worked on the faceting machine :- ) Did some cable work and made the compressor for the tool changers, just watch the video. Hope to do some more next time!

See ya around! If there still watching some people. (I hope)

Greets,

Christian

Thanks Gill! Im also still looking for materials for the new cnc machine. Next friday my friend comes and he is taking me to a whole sale of industrial things mayby i can get some aluminium and some other things for the faceting machine but also for the cnc router. But there is some progress in the machine smile

Yes thats right! But i dont stand still! I finaly managed to control the motors perfectly in a graph (schematic) so i need to wire up my microcontoller and do some programming now, but i will make a new video of where i am now. Im also waiting for some things where i made some drawings for such as 20x conus for the automatic tool changer and 16 pieces 8mm underlay laps 200mm in diameter and some other things. In the meanwhile im also lerning much about pneumatics. So all the short movements will be done by pneumatics.

All with all, i soon can do the motors, i wrote a piece of software to control 7 motors at once but not yet synchronously but also got a good solution to do this also! But requires an SD card to run beqourse the amount of data that it is using and the speed (1 megabyte per second).

So these functions can i use for all 7 motors:

- Homeing
- Positioning
- Repeation Number
- Continuous Repeation

These are the first ill program, ive redone this 3 times now and i had first 500 programming rules for doing the motor steps, speed controlled etc... a week later i did it again but in 50 programming rules. And last week i did the same thing in 4 programming rules and now it is all working perfect!

Hope that my aluminium undelayment discs (laps) are done next week and then ill will make a new video. Did a lot of work lately!

Greets,

Christian

Sounds pretty nice Christian.
Hope to see the underlayment discs in motion soon.
Is the machine going to be able to change the laps by itself too?

Me too yes it is still a function i want to have in the machine to automatic change the laps!
First i need to solder de teensy mcu for programming the beast :- ) Still have a lot to program...

Hi Christian.

Are you going to use those underlayment laps directly under the sintered laps used for faceting?
Why so big?
Why so many?
Are you planing to fit the sintered lap together with the underlayment maybe?

Hi,

Ill first going to use those for china laps sintered laps are around 1000 euro's each... big? 200mm in diameter and 16 in total for the lap changer :- ) im going to glue the cheap china laps for test onto the underlayment laps. And if i need to replace them ill use acetone to remove them off the base laps.

Greets,

Christian

Ok, now I get it. If you are going to glue the cheap ones to the underlayment then they have to be that big.
How precise is the run out going to be on the lap when glued?

Why don’t you use normal laps to begin with instead of sintered?

Those china laps are 10-20 euro each?! So these ill use for test :- ) they work, they arent that greath but good inaf for testing. Sintered laps are too expensive but works a lifetime but dont have 1000 euro's for each lap tongue so ill use the cheap ones for testing and some laps from BATT laps. But also those costs around 200-300 usd each.

I can glue them together under preasure so dont think the runout will be that high. But testing should tell tongue
