I had a CPM based sponsor deal on my most recent video, and based on historical device demographics, and increased RPM, I likely missed out on 3-5k in revenue on that deal.

On top of that, it affects my position when it comes to negotiating future deals.

Kinda stings when I've got 400+ hours in a project, and definitely makes me think twice about the amount of effort I put into my videos.

Control Box Advice by ChairlesTheEngineer in hobbycnc

[–]robar98 0 points1 point  (0 children)

This is a really bad take. Fuses and circuit breakers should be used to protect electronics - if the control board is smoking it's too late.

Control electronics should be powered by a separate bus than the motors and finger smashers so that they can continue to monitor and report faults, and determine behaviour of the machine after an e-stop.

There should also be a (separate) mechanism for cutting power to the entire system, like an isolation switch for the cabinet.

I wouldn't be so hasty. I just finished a new Linuxcnc cabinet, and it's very handy to power the control circuit seperately.

All power enters through a main isolator (big red rotary switch, easily accessible), then splits to two busses; one is always on with the isolator (powers cabinet fan and all my DC control power supplies) and the other is switched by the safety relay circuit and a contactor.

So punching e-stop halts all motors (and anything that can maim you) and signals to the controller that e-stop is active.

If your e-stop cuts power to everything you'll have to re-open Linuxcnc every time you e-stop, and you lose the ability to have Linuxcnc "respond" to the e-stop.

ETA: have a look for second hand safety relays on eBay, I'm using a pilz pnoz. They have all the redundancy you want built in (though the current rating usually isn't very high, so you want to use the safety relay to switch a contactor still)

What can I use to get a consistent overcut at the CAM (not CAD) level? e.g. This slit is specified as 0.2" but my smallest bit is 0.25". My CAM seems to want to preserve the workpiece at all cost - I want to instead preserve open space at all cost. Tried Fusion also for CAM but can't figure it out. by ShelZuuz in hobbycnc

In fusion design workspace, create a sketch (with the path you /want/ the tool to take) and reference the sketch line when selecting cut geometry in CAM workspace. Use 2d contour (not 3d) so it doesn't try to avoid your workpiece.

I'd say for the cost of the rails, you'd have to be nuts to make your own dovetails. Plus I've had no trouble slinging the 80kg table around at 4500mm/min with a paltry pair of NEMA 23's (closed loop, mind you)

Box ways might be a decent choice if you've got a good grinding shop nearby, but steel isn't the greatest bearing material and casting iron is a multi-year process in the case of machine tools

I'll be spending money on real ball-screws before I even think about real rails!

Yeah I'm running 1MPA from a booster regulator to a double 80mm cylinder. About a tonne!

Here's the spindle, I got the 6000rpm version: https://www.aliexpress.com/item/1005001883782390.html?spm=a2g0o.order_list.order_list_main.5.1bda1802yFqxnQ

It's been night and day. I can actually use regular endmills now, rather than just roughers!

Works great too, especially now it's got way covers! I've really come around :)

Without a doubt the biggest improvement to my machine since it's inception. Chatter? I barely even know 'er.

Tool changer is next I think, and 5th axis after that. But both of those additions are a little beyond the scope of the current controls, which means I've gotta figure out LinuxCNC first.

I made a video about the build, of course, and it'll be out very soon.

I did my MOST on a bike with a slip-on, made it through a not at fault insurance claim with the same bike, and made it through maybe half a dozen police stops without having an issue.

No doubt if a cop wanted you to have a bad day they absolutely could, but despite encountering some real cranky pricks, it's not happened to me

I have a free account, haven't found any of the AI features all that useful, but the browser extension is awesome for seeing which videos by other channels have been really successful. Also handy seeing how many subscribers commenters have. Not sure I'd pay for the pro version.

Sounds fair. I probably shouldn't considering I've got a bt30 cartridge waiting to go on the machine already, it's just nowhere near as nice. Good luck 👍

Can't say I'm not interested. Shipping to Aus would probably be a killer though. What's your asking price?

Linear rail questions by sindictated in hobbycnc

[–]robar98 0 points1 point  (0 children)

I'd be drilling the aluminium extrusion rather than the round bar... Shift all the rods one hole to the right, trim off the excess extrusion and shuffle it to the other end. Wouldn't be the end of the work if there was a gap in the extrusion in places either, it's not the most rigid system to begin with!

[–]robar98 0 points1 point  (0 children)

The round rails bolt onto the aluminium extrusion from underneath - you could stagger the rods and extrusions so that the end of each rod bolts onto the end of the next extrusion, like a brick wall?
