Bargain Basement / NEW Rotary 4th Axis, ZERO Backlash, Duplex Worm Drive

« on: July 09, 2018, 08:28:19 AM »

Hello Guys,

I would like to announce a NEW product we've been working on lately, and which is soon going to be available for purchase. I am making this announcement after which have been testing and using the final prototypes for quite some time now, machining all sorts of super precision parts from aluminum, brass, steel, stainless steel and plastics, and we are very pleased with the performance we've been witnessing. This is a unique Rotary Axis, one of its kind to utilize Duplex Worm drive in this scale and price range. Duplex Worm drives are long used in the higher end large scale expensive industrial equipment. Our goal was to make it affordable for everyone wanting a great Rotary Axis while benefiting industrial performance and precision. Thanks to its Duplex Worm drive it has ZERO backlash, while contrary to timing belt drives (which also considered to be zero backlash), it also benefits the back locking inherent feature of a worm drive, meaning hard materials and deep cuts can be made without the risk of the axis losing position. Whilst utilizing a small (NEMA17) stepper motor to save space, it is still capable of providing a HUGE 15Nm torque for its size. No timing belt driven rotary axes in this scale can approach this number.


As standard it is going to be provided with an ER25 collet chuck and a 17mm through hole to allow the use of bar stock. Provision has been made to fit an 80mm chuck, which will be available later on. The Body is solid Aluminum alloy, black hard anodized. The Rotary Axis was specifically designed with small machines in mind and the body size is 100x100x60 mm, so that it can easily fit the smallest of machines, whilst still providing the user the luxury of an expensive industrial device. Also can be easily used on larger machines for precision jobs.


Now the Bonus part: The Rotary Axis will be initially offered for a limited time on a pre-sale for members of the group. In the presale it will be offered for 50%(!!) of the final retail price, which is estimated at around 600 USD. It means that you can get it for as little as 300 USD on the presale!!! Only a limited QTY will be offered for a limited time on the presale, just as introduction for this new product of ours. Stay tuned 


Thanks,
Dan

General Mach Discussion / PicEngrave & Impact Engraving

« on: August 22, 2016, 08:09:02 AM »

Hi,

Does anybody know if PicEngrave can be used for impact engraving? If so, any reference on how to do this?

Any other alternatives aside from the Impact Engraving plugin? I know Dot-G does it, but seems a bit low on resolution.

PoKeys / Pokeys57CNC Strange Jogging Behaviour

« on: May 31, 2016, 06:02:40 AM »

Hi,

Using pokeys 4.1.64, Mach3 xx.066. Having a strange behaviour. Mostly happens after homing not limited to it. Home the axis, then jog the axis off the switch using the keyboard, release the arrow key and the axis bumps and stops as if there was no deceleration. On subsequent jog moves it would act normally, i.e. decelerating according to the defined rate to a stop. Occasionally it would happen again, but as I said, mostly (not always happens here too) after homing was issued.

Seems like a bug to me.

PoKeys / PoKeys57CNC and Mach3 Softlimits

« on: February 02, 2016, 03:15:09 PM »

Hi,

Should softlimits work with this setup? I am not able to turn softlimits on in Mach3. Getting the message that I am beyond limits, although I am within the defined envelope.

Thanks,

Bargain Basement / CSMIO/IP-A + ENC Module

« on: December 15, 2015, 11:57:10 AM »

Bought it 3 years ago. Was intending to retrofit a lathe. The lathe has since been sold as is and the controller has been lying on the shelf waiting for another possible project which never happened. It has been bench tested and found to be working, otherwise never used. It is the CSMIO/IP-A controller including the ENC module for threading. Asking $630 for the two, not including the postage fee.

Thanks,

Mach4 General Discussion / Mach4 Executing Gcode from LUA

« on: May 25, 2015, 06:37:04 AM »

Trying to execute Gcode from LUA. This script works fine:

local inst = mc.mcGetInstance()
mc.mcCntlGcodeExecute(inst, "G0 X10 Y10\n")

However, with the below function, the numbers in the DROs do not continuously update, but only when the final destination is reached.

local inst = mc.mcGetInstance()
mc.mcCntlGcodeExecuteWait(inst, "G0 X10 Y10\n")

When trying to execute two line of Gcode, like below, the DROs again don't update continously, but only when the final point is reached.

local inst = mc.mcGetInstance()
mc.mcCntlGcodeExecute(inst, "G0 X10 Y10\n")
mc.mcCntlGcodeExecute(inst, "G0 X5 Y5\n")

What is the correct way to programm in order for the DROs to continuously update?

Mach4 General Discussion / Mach4 How to Change #Variable value from LUA

« on: May 24, 2015, 03:00:24 PM »

Trying to set a #Variable value by a script in a button. As per the Mach4 Scripting Manual, I have created this function in the ScreenLoad Script:

function WriteRegister(regname, regvalue)
  local inst = mc.mcGetInstance()
  local hreg = mc.mcRegGetHandle(inst, string.format("#Variables/%s", regname))
  mc.mcRegSetValueString(hreg, tostring(regvalue))
end

And in the buttin script I have this:

WriteRegister("#1", 15)

However, clicking the button doesn't change the value of #1 to 15. Following the example above, tried change iRegs0 and Sim0 register values and it worked fine, but not with #Variables. How should it be done?

General Mach Discussion / AC Servo Spindle and ESS

« on: April 14, 2015, 03:10:44 AM »

Hi,

Have fitted an AC servo to a large spindle (380mm chuck). It uses an ESS as a controller. Trouble is, when spindle runs, hitting the Stop in Mach causes an abrupt stop of the pulse train to the servo drive and it instantaneously stops. With a chuck that big, it means tearing the belt and causing other damage. With the USB SS it has never been an issue (have it on two machines) and hitting Stop still smoothly decelerates to a stop.

Hood, I am sure you encountered this on your Computurn with the large chuck prior to switching to CSMIO. How did you solve this?

Thanks,
Dan
