CamBam help (General usage) / Re: Highlighted Operation

A very precious feature. And somewhat hidden from the user.
I don't remember whether I discovered it myself or was given a clue from a forum member (David perhaps).
I included it in the default CB template and every new project has the option set by default.
If you need to see more than one toolpath Ctrl-click and selected toolpats will be visible. Even from different parts.

Thank you David.  I was not looking in the right spot. 

Personally, I just disable all the MOps except the one I wish to see, Bob.  If there's a better way, I'd love to know it, too!

LLoyd, the most frustrating part is I am pretty sure I have used the feature before.

hello

A video ;)


https://www.screencast.com/t/8yaFfOPE

with those settings, if you select a mop, you get the toolpath for only this mop, if you select a CamPart you get all the toolpath for the CamPart.

you can use the mouse wheel after you have clicked in the "toolpath number" box to change the value.

edit: and I forgot ... Toolpath visibility set to Selected only.

CamBam help (General usage) / Highlighted Operation

I've never used this view option, but I have seen it mentioned a couple times.  How do you set CB to just show the toolpaths for the currently highlighted operation without turning off all the other operations? 

I did a quick look, but I must have missed it.

I have a battery powered digital thermometer whose probe is attached to the spindle body with insulation tape. Allows me to watch the spindle temperature and saved it once when the circulation pump failed.

Yes, already on the shopping list.

I was off gallavanting about England for a week but back on the pitch now!

...For what you want to do it’s not worth the effort to use step files...........The STL format is old but it’s it’s an open standard, newer programs are transitioning to AMF (the 3D printing crowd are all over it) which is better in every way.

Will check that out.

I don’t know about Alibre, It has a somewhat checkered history, that software has been bought and sold a few times,.....

Old stuff I read said it was it could be a bit buggy bit buggy. I have several friend that use it and recommended it. I tried the demos of a few others and it seemed pretty good to me and has a pretty good user forum. As a hobbyist and less frequent user the perpetual license and (lower) cost of ownership ownership made it look like a good value for me comparedto packages that were $1000s to buy and maintain.

In short use a stl and dig around in Alibre to find the working with mesh’s doc. Some programs like Prusa slicer (free) will automatically on loading the file repair it and on occasions I’ve had a stl file that I could not fix and running through the slicer it was repaired. Alibre may already do this, I don’t know. It’ll be a matter of trial-and-error finding what works best for you, just reduce the stl triangle count until it’s not usable in CB .....

I'll experiment.

Thanks again.

Best,
Kelly

When I set a HY VFD for a friend, some years ago I have had a similar problem because the value for the frequency range (PD005/PD011) was not the same that the range of the potentiometer (PD072/PD073) and I can't get the max speed with it .... but it seems that it's OK in your settings.

Another things to know is that if you are using the potentiometer on the VFD panel to set the speed, the voltage must be 0-5V (PD070 = 1)

If you're using the BoB+soft to set the speed (in this case the VFD panel potentiometer is disabled), of course PD070 must be set to match what the bob needs (mostly 0-10V)

I'm going with it being the PD070 not set to 1!

After noting many commentators claimed their spindle arrived without being earthed, I deceided it would be safer to open up the spindle and check, delighted to say it was though the choice of colour for the wire was interesting, nevertheless all OK. 

I'm glad I did take the cover off though as there was a large hair & dirt surrounded by grease in the water coolent hole, gently removed with a cocktail stick. How or why this got in, anyway it was worth checking just for this.

All back together and now working as it should.

We were that busy for a while we switched to outsourced laser cutting to cope and our machine sat idle for months.  I think this is the route of the problem.

There are two things to consider there,

1. The capacitors in the VFD have to be 'formed' if they have not been energised for a while. This entails leaving the VDF running as you mention.
2. The other is the spindle bearings, these should be exercised regularly starting at a slow speed then gradually increased over a period of time, such as 10 minutes, to full speed.

Thanks

One thing I noted warming mine up for over an hour, first time new one turned on, it didn't even get warm. In contrast to the now expired spindle which warmed to the touch very quickly. Clearly the signs this spindle was on the way out were there, clearly on hindsight I contributed to it's demise.

It's ben an expensive lesson but as with all lessons, one worth learning not to be forgotten.
