Show"N"Tell ( What you have made with your CNC machine.) / Machined an Iphone 5

« on: February 09, 2014, 07:24:02 AM »

machined an iphone5 just as a bit of a fun project







I blacked the engraving on the back to make it stand out more





then I got pressured to put it on ebay by some friends lol

http://www.ebay.co.uk/itm/281262248062?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1586.l2649

the details on how it was made

I first borrowed a friends phone and drew an exact copy in autoCAD, then I used cambam to generate the code then mach3 to machine.

ive got a denford triac vmc, with 6 station atc and coolant flood

hope people like my project

Tangent Corner / X Axis missing steps

« on: November 29, 2013, 02:46:57 PM »

ok so the story goes, I have a denford triac, had it for about a year now. been upgrading the electronics as and when I can afford it and current I have a smooth stepper and PMDX-126 installed. the machine has been fully converted to mach3 with mach standard mill screen set

not that im suggesting the electronics are the cause but

a few months ago the x axis started playing up, when going full speed it was missing steps and you could hear the table making a donk donk donk noise when doing a g00 command. did a little bit of faffing with the machine and thought the stepper motor was like 15 years old it probably just needs replacing, so I got an identical replacement and all was well.

then about a month later the x axis started playing up again and started missing steps, which is strange as the stepper was brand new. now the stepper motor is this one -

I got the smallest one as my drive cards only gives out a max of 2amps.

the stepper is an 8 wire stepper but the machine only have a connection for 4 wires, I wired the new stepper exactly the same as the old one, only using 4 wires/coils. I cant have damaged the stepper as its rated for 3.1amp and the card only gives out 2amps.

so as a test I wired the other 4 coils in that I hadn't been using and it worked fine, it stop skipping steps. then a few days later bang missing steps again and the table is making a donking noise.

I tested everything in the control cabinet and I cannot get this issue to happen on the y axis. someone has mentioned that there are some debounce settings in the smooth stepper.

can anyone give me any info about these settings and where are they, could they help solve my problem

this vid 10 seconds in you can just about hear the problem

Tangent Corner / Vacuum Tables?

« on: October 30, 2013, 01:29:14 PM »

hi all,

im interested in a vacuum table setup, I have a compressor for my cnc as that drives the atc.

its a bambi 50L 8bar jobby

ive seen these -

http://www.clampusystems.com/Ventrui.htmlhttp://www.clampusystems.com/Ventrui.html

I have emailed the place but they haven't got back to me, are these what I think they are? they use a compressor to generate a vacuum for a table?

I do cnc'ing as a hobby at the moment I sit in an office all week long. I thought it would be good to make myself an object for my desk at work and came across this on youtube

anyone got any thoughts on getting this working with mach3 as part of an atc?

just purchased a machine without atc so am keen to add one

General Mach Discussion / Re: axis limits and spindle stopping

« on: May 31, 2013, 06:21:20 AM »

it only happens when im using the hand wheel and on the y axis, go to far and spindle stops. I was hoping there might just be a tick box or something in mach to change this

Limit switch / homing switch pfff all the same ;-)

 I'm not sure if the table is reaching its limits or hitting the homing switch but either way the spindle stops. So is there a way to change this as its very annoying and not needed
