In my days machining blow molds there were lots of parts where I had to make a completely through hole. Sometimes those were up to 4 inches deep and I had to go from both sides!

The trick to machining cores like that is to leave about 0.05" on skin all around AND pick milling direction and start point such that when the last bit is milled through, the core gently pushed away from the cutter instead of jumping out.

ProLIGHT 2000 retrofit. Installing All the components.

September 11, 2020, 9:01 pm by Eldar Gerfanov

Having done all the motor tuning and testing on the table, it was time to mount everything inside the machine enclosure.

I cut the heatsink to size enough to house four drivers, laid out some mounting holes, and drilled and tapped them M3.
Then drilled clearance holes in both the heatsink and the board and joined them with some 19mm long brass standoffs.

Drilled a hole in the enclosure for the motion controller mounting and LAN cable connection.

Then the main board containing drives and the power board and the breakout board were installed in the machine.
At this point, I realized the drive mounting scheme I chose was a mistake because it was a lot more challenging to connect the wires to the drive terminals so deep and so close to the enclosure. It helped to unscrew the main board, pull it out a little, connect the wires and only then push it back in and screw it to the wall of the enclosure.

Traced all the black cable going to the fuses and found which ones control the spindle and which ones go to the appliance plugs.
By fiddling with the controls on the front of the machine, identified all the wires and their functionality.

The Gecko G320X drives use the same (ERR/RES) pin controlling the drive fault reset and the error status.
When the drive is at fault (every time you startup or when the motor loses too many counts), it has a ground voltage of 0. If you pass +5v, it will reset the fault and enable the drive.

So I had to re-use the red cycle stop button to pul it to +5V when the machine is started. To sense the drive fault and stop the machine I used pin 12 (pull-down) on the C11G BOB. So when any of the drives pull ERR/RES to ground, the C11G board and mach4 react to it like an E-STOP.

The motors mounted back, and the encoder wires soldered directly to the data cable wires of the same colors. For that, I cut off the bulky DB-25 connectors.

Pay attention to the property belt tensioning. According to the manufacturer, the belt should sag a maximum of 1mm under the pressure of about 3 pounds applied at its middle point.

With everything connected, it is time to test the machine. See how it homes and runs!

proLIGHT 2000 Retrofit. Wiring new components.

September 5, 2020, 7:19 pm by Eldar Gerfanov

Finally got all the parts a coulple of days ago and by now have connected everything on the table.

By accident ordered a wrong mounting plate for the encoders and decided to design and 3d print themon my own. In the morning I had 3 brand new encoder mountings!  

By trial and error figured that it is best to leave the default encoder count to 2048 PPR. With that set, the servos are very stiff yet quiet. Almost no dithering.

Managed to connect the spindle control and have it turning CW at programmed speed. Yet can't figure out how to run it backwards:(

ProLIGHT 2000 retrofit!

August 20, 2020, 7:20 am by Eldar Gerfanov

I have been hunting for a very rigid but small machine for the last year or so.

And when I finally found one for sale on an auction in Minnesota, I could not pass.

Now the machine is in my garage.

It is a surprisingly heavy machine with a solid epoxy granite frame.

The features are as follows:

  • 1.5HP 5000 RPM spindle
  • Closed loop servos on all axes
  • Power draw bar and a rack tool changer assembly

I built a table with casters for it and upon plugging it to a computer it turned out that.... It's dead!

The proprietary Animatics control in the back is not working, which means 95% of all electronics in the back must be replaced.

I was actually almost hoping for that because the original software is DOS-only. It is hardly convenient to work with it.

I want it to work under mach or LinuxCNC

So I ordered the required parts online and when all of them are here, I will start the retrofit process.

I will be documenting my process in comments.

Wish me luck!

HSMAdvisor/FSWizard got featured on DIY Engineering!

It seems like HSMAdvisor's machine profile settings and power compensation work just fine even for as small of a CNC machines as  Nomad  Carbide 3D:


Importing Fusion 360 Tool Libraries into HSMAdvisor

August 11, 2020, 2:18 pm by Eldar Gerfanov

Great news for our many Fusion 360 users!

Starting with HSMAdvisor v2.1.0, you can import F360 hsmlib files into the HSMAdvisor database.
Holder import is not yet supported, but I will add it in one of the next updates.

Not sure what to do with allowing HSMAdvisor to export tools into F360...
Please let me know if you are interested in this functionality, and I will work on it.

Take it for a ride and let me know if there are any issues with it!

Cheers!

HSMAdvisor v2.0.2

August 8, 2020, 4:11 pm by Eldar Gerfanov

I just uploaded a new standalone and Mastercam 2021 hook version of HSMAdvisor Machinist Calculator.

In it fixed the issue with the loading of older database files and updating DB UI.

Also from this point on HSMAdvisor will switch to Semantic Versioning in the following format: major.minor.build

  • Major: big update that makes older version non-forward compatible.
  • Minor: a minor update that does not break any existing functionality
  • Build: a bug-fix that does not add new features, but fixes the existing ones

Check out the latest version here: https://hsmadvisor.com/?page=Download

Have an enjoyable and safe weekend, everybody!

In version 2 we tried to keep the familiar layout of HSMAdvisor.

HSMAdvisor 2 is currently at the "Release Candidate" stage.
Every month I will be publishing an update that will reset its trial counter, so people can use it for free until it is finally production-ready.

The best thing of all is HSMAdvisor 2 license is completely compatible with its predecessor!

FSWizard1.7.9.PNG

Centerdrill Calculator added in FSWizard 1.7.9!

Check it out at https://fswizard.com

Calculator shows reference for Imperial and Metric centerdrills and allows to calculate the depth of the drilled hole based on the countersink hole diameter and vise-versa.

Also this new version features better support for wide screens.
The input fields are now stacked in 3 columns when screen width is large enough to fit them.

If you want to sign up for the beta test, please read here: https://zero-divide.net/?shell_id=151&article_id=5271_free-fswizard-pro-for-everybody

Cheers!
