That was an awesome video! I seriously learned the type of things im looking to learn! Please please dont stop haha i love coding

Great ideas, I found it very interesting.

very nice job sir. cheers

Good explanation

Hllo sir ... can use arduino ?

Hi Sir, Just curious how do you keep track of the tool positions ? Are you tracking and homing tool #1 and then proceed with the tool change ? I noticed there is no line of code tracking some sort on tool position. Do you have to manually position to tool one when you first initialize the turret ?

Hi Rengan no need for tracking as yet. as the macro just takes the tool number from (1200) and make its calculation from there. as the tool changer is set up to run just like a 4th axis it just moves to a set degree. i.e tool 1 000, tool 2 045, tool 3 090. etc. it doesn't need to know where it is or has been like the (click) type tool changers. as for "Do you have to manually position to tool one when you first initialize the turret ?" when mach is first opened the tool is 0. just manually enter the tool that is in position at that time. I tend to leave it in tool 1 when i shut down mach. But..... I think there may be a problem over time. as if you are using micro stepping and lets say tool 1 is between a full step. when you power off your stepper motor will jump to the nearest step. so when you power back on your stepper wont be in the same place. do this a few times and i think it will eventually be out of line with the locking teeth. when i finally get this on a lathe, I will have to come up with a homing switch and homing macro. so when you press the homing button the Z,X axis will home. The tool changer will open, rotate till it hits some switch. then move the other way "?" amount to line up with tool 1. closes the changer, then puts 1 in (1200). everything should now be homed.

Hello, are there any .dwg drawings of metal elements available?

Fantastic video and very interesting. I'm just embarking on building a similar turret myself. Would you happen to have a link to where you bought the springs form and which ones? Thanks

Hi David, thanks for the comment. sorry but i can't give you the exact details you need. but i got the springs from here advanex.co.uk/product/compression-springs/. seems they have changed there website. Have found this place www.leespring.co.uk/compression-springs. just enter what you need. the springs in there at the mo are......12.7mm dia, 63.5mm long, 1.7mm wire. and I used 3 springs not 6. hope this helps.

@@davidimurray 1) It works, that's all i can say at the mo, as i haven't built the lathe it goes onto yet. The tool disk has been turned up, but no milling done to it as yet. when i have finished it, it should turn out like the one Tormach has for there lathe. with the coolant holes as well. but will be able to mount the tools face up or face down. 2) curvic coupling, the disk blanks were made on the lathe. then put on a cnc mill to cut the interlocking bits out. there a few ways i have seen this being done. you could put both rings together, drill ream 8 10mm holes and put 10mm dowels on the fixed side. 3) the only thing i would change is how i did the bearing mounts. these i did so they would be screwed to the inside of the box. this means the inside walls have to be machined parallel. this is relay hard to do unless you have a 150mm long end mill, or a shaper. if you look in this video @1:38 you can see what i mean.... just left of the belt. The black bit of delrin on the other side is covering up the other mount on the outside of the box. this was the only way i could get the bushes to line up. if both was on the out side they would be inline and parallel with no alignment needed. hope that made sense.

HI Tony, the tool changer is set up just like a conventional A axis. so the macro just tells the stepper to go to a set degree and i think Mach just works out the rest, as i have DRO mapped to the A axis and it gets up to some silly numbers. if you send it back to tool 1 it goes back to tool 1 but the DRO will read 2340 for e.g. any number it ends up at is a multiple of 45. There is a setting under Mach (General config, Rotational> ROT 360 rollover) This needs be ether checked or unchecked to get this macro to work. not much help i know, but the lathe pc is not up and running at the mo. hope this helped.

Sir, your OEMDRO(1200) is custom defined or mach3 defined ? I searched through Mach3_V3.x_Macro_Prog_Ref.pdf and can only get up to OEM DRO Tool Length (current) 836. Am I referring to an obsolete document ?

@blightysbits

Hi Rengan, I'm not a 100% on that one. your PDF and everything else i have looked at today says it should be 824. cant find any reference to 1200 apart from its in every tool changer macro i've seen. As you use 24 as the "standard code" i would say its mach defined.

i have seen vids of pokeys do treading with an index pulse on mach3. with mach4 you use an encoder. if your using mach3 i would suggest using G76 for treading and not G32. I have found that G32 tends to go a bit off after a few cuts.
