Feeling particularly fond of GF after this weekend


#1

So it’s only tangentially related, but I recently ordered an x-carve and spent part of the weekend working on assembling it. I’ve got it about halfway complete (I take lots of breaks) and the folks at Inventables did a great job on the build instructions, but it has still made me incredibly grateful that the Glowforge will be arriving assembled.

I didn’t even know that M2 split lock washers existed before this weekend and frankly, even after handling them, I’m still not convinced.

So @dan et al, take your time, because I want my forge built right and better you than me.

I’ve broken 4 of the Z axis micro switches in 3 months. Get a 10 pack of cheap spares from China. It’s pretty easy to type in 1.0 inches instead of 0.1 inches or some such mistake. The Z axis V-wheel will break the switch every time. But it’s still fun.


#3

I want a larger format CNC router but I hate microswitches. I hope that by the time I do build it someone has worked out inductive or opto zero switches or perhaps I’ll work out a striker plate to zero all 3 axises off the bit.


#4

LMAO - I have opto switches on my K40 and most of the people in the forums are trying to replace those with micro switches. :smile: It’s like “I want what I don’t have and don’t want what I do” :slight_smile:

Right? We just know of the hassles of what we have. The best working thing I have experienced it the V2 of the handibot. It jams the axis up aginst a hard stop. What it does internally I don’t know, reads current flow? Anyway, they have completely eliminated switches.


#6

Those switches are worthless. I’ve busted the Z switch every time I’ve used Easel since it wants to home during the setup process. (watch your eyes - those things explode into a shower of tiny pieces)

Early on I moved to VCarve, so now the only time I’ve broken them it was my own dumb fault. My Z switch has sat broken for months yet I have a bag full of new switches in a drawer. That shows how useful they are,


#7

No end stop detection at all, other than the funny noises it makes when it hits the limit of travel, on my little CNC machine. I have hit the ends a couple of times without any real damage, it just pushes everything out of square which, of course, is a right PITA.

I got my X carve last week (haven’t opened the box). Was trying to finish my 3d printer but hit a roadblock when I found the z-axis switch missing :anguished:. See if China responds… Maybe this upcoming 3-day weekend I’ll look at the xcarve.
You are sooooo right about the GF though - making it "user friendly’ is an unbelievable plus. When I hear them talking about cutting 30 minutes after opening the box :astonished:. ( Still fiddling with the K40 and it’s been months). Plus the fact that the members here can be an unbelievable resource for any issues or ideas !


#9

Oh, teeny tiny switches, how I hate you. I got it into my head that tiny reed switches were something I needed in my life, having absolutely no experience in anything relevant.

Turns out I’m really good at breaking reed switches and not really very good at soldering.


#10

Dump the microswitch style homing/limit switches to go inductive.

One in the long list of annoying ‘feature sets’ of GRBL is manually specifying a MC that it knows it should not goto and going anyway. LinuxCNC/Mach3 would approach the closest specified coordinate then just stop. Thou GRBL does support soft limits- it does not stop end-user goof ups.


#11

Sure, but I could just not make any mistakes, right?
… right, gang?
…why is everyone laughing?
