Being almost ready to order a mill, I went to the Novakon web page looking for information and specs for the series 3 machine. No real information was available and the web page is, at best, useless. Is there any other site with real information and specs for the machine?
Thanks,
John
Hi John,
Thank you for bringing this to our attention and we apologize for any inconvenience. The information spec link was temporarily deactivated during the web site designing. The product information is now listed with the product descriptions. There will be further updates as the web site is finalized.
Regards,
Novakon Team
Novakon Team,
Go to the website yourselves and try to find some useful information on the NM200 Toro Pro. E.g., does it support rigid tapping? What software is included, what control program is included, time lag from ordering until delivery.
Creating a functional and useful web page isn't rocket science. A flaky website could be considered the product of a flaky business. Get it up and running and you might sell more machines.

yeah, the new site seems to be messed up a bit still.
the machine uses steppers and an indcution motor for a spindle. you have to supply a computer which is the control (or buy one from novakon).
on the old machines, it would have come with mach3. i would assume the new one is the same, but i dont see it mentioned explcitely. mach 3 does NOT support rigid tapping, however with careful testing, you can make use of a compression(floating) tap holder and use g84 to tap. you woul dneed a servo spindle motor and emc2 on linux to do proper rigid tapping, although people have found some clever ways for mach3 to do it as well (still requiring a servo).
hopefully they get this all onto the website again, it was all there a few weeks ago.
in any case though, if you need to know specs, just email them. its alot easier than ranting on a forum about it

Good point! Sorry about coming across as a rant.

You do not need a servo motor on the spindle to rigid tap with linuxcnc. You do need a 3 channel encoder. (A, B, Z) channels. Linuxcnc 'gears' the axis with the spindle using the encoder.

thats sync tapping, not rigid, but thats quite good enough. i didnt know emc had that function. thats basically how lathe threading is done as well right?

I have acutally never heard of sync tapping.. It has always been rigid tapping. Gearing the axis to the spindle encoder is how lots commercial cnc's do it. I have not had any issues with linuxcnc and rigid tapping. I have tapped from 1 inch down to 10-32 on my large hmc with no broken taps yet

using a multi line encoder on a lathe also has its advantages like..

synchromous tapping is timing the axis to the spindle with an encoder - like a lather, or the emc tapping you show.
rigid tapping is true controlled coordinated motion as if the spindle was a rotary axis.
in most cases sync tapping is more than adequate. its only when you need an exact thread depth, that rigid tapping would be required.
anyhoo, thats a cool video. thanks.

Heh - I asked on the linuxcnc list for grins what the difference between rigid tapping and sync (synchronous tapping) and one of the developers found this.
Re: synchronous vs rigid tapping
It looks like you have it reversed.
synchronous - using a servo on the spindle and command the axis to move together. At this time (without external hardware) this is the only way mach can tap. ie - commanding the a axis (spindle) and z axis to move.
Rigid tapping - Running the spindle normally and electronically gearing the axis to follow. (like lots of commercial machines do) Linuxcnc can do both if you wanted to but just adding a encoder to your existing spindle seems to be the easiest. (as long as your axis can keep up with the spindle reversals.)

lies, all lies!

interesting. i guess i have always had it backwards. in practice its modtly irrelevant except in rare cases you need to control depth precisely.
now why cant mach3 do this? it can do threading with an encoder on the spindle, tapping should be the same internally.

That is ok. I usually get lots of things wrong
Mach (as far as I know) can only use a 1 ppr 'encoder' on the spindle. Not enough pulses to do rigid tapping. You can get external hardware like kmotion or such that does the gearing in hardware with an encoder . Again - from what I understand
