Yup, done all of those quite successfully!
Thanks for the replies folks.

Yeah, I thought it might be the case that the spindle wasn’t the only constraint. Sigh… looks like I have to buy more tools. OH NO! Lol

I’ve done a lot of reading on shopbots (especially the desktop) and working with steel. I’d like to get some vise style hold downs and tackle some light stainless (think 416 and 17-4) work. Think...

So I had a LOT of success with these new ramp settings in 3D! I did a HUGE several-hour run with no issues. Along with a couple other smaller 3D runs. All went off without a hitch.
Need to remember...

So far with the new software and firmware upgrades and VR settings my tests are going well (even at my old feed rates!... no point in changing everything at once or else it'll be hard to tell what...

@srwtlc the ramps learning link doesn't seem to be working?
Best,
Chris

Been MAD busy. But I’m most way through reading the suggested materials and making changes. Hoping to find time to run a bunch of tests soon too if the day-job will chill out. Will keep you all...

Yeah, I'm a little behind hahaha. I'm running 3.8.14 which is just what came on the original install when I bought the machine (eg: I've never updated it ops). Firmware version is 220.
I just...

Packet_ET - 16.5 (ms;good<20)
No idea what that means though hahaha.

It has indeed been awhile but I've been doing mostly 2D work with my machine and therefore I guess I just wasn't seeing it...

So this appears to be back... whether I just got lucky for awhile, or it was happening in smaller amounts to a point I couldn't tell as readily, or I just don't use my machine that often (probably...

I've only ever messed with MY particular Shopbot CNC. I was running a path with the spindle off as a simple test before cutting things with it; just watch to make sure it looks like it's doing things...

As dumb as it sounds I keyed into the "check your cables" part of the error... The laptop that runs my shopbot sits on a slide-out tray connected to the table the CNC is on. Lately I've been using...

Hey guys. I was running my Desktop (which gets run only rarely since I just use it for hobby stuff) and low and behold I have yet another problem. Seems every other time I use the machine I encounter...

Thanks guys!
I'm usually pretty happy to experiment. My concern here is more financial than anything else. I'm currently using 1.4" bits (relatively cheap enough), but would like to upgrade to some...

Anyone on problem 1?
Chris
PS: Thanks Don for the info on deflection eg: Problem 2!

A little more info since I've been spending the morning experimenting. I've found that for the 57-910 I'm indeed getting nice surfaces in the recommended range; small success! So I've been doing more...

I did some more experimenting by milling slots and circles at .4" deep in two passes. I tried a .005 and .007 chipload (per onsrud recommendations) for both my single-flute bits (one new, one...

Hey guys, I did some searching and couldn't seem to find answers here. My two current issues seem to be:
1- Lower-than-expected surface quality at less than half bit's recommended chipload
2- Poor...

Alright, so new tests running 2-flute bits faster. Not apples-to-apples since I snapped my only up-cut straight bit at the very start of this test (don't ask). So this was a down-cut 2-flute that...

Luckily, most of the CNC-centric stuff on my current set of builds got done, so I haven't had much to throw on there and try and push it. Once I knock out all this stupid sanding work I have to do...

I used to run them faster Kyle, but ran into the problems I discussed in this thread: http://www.talkshopbot.com/forum/showthread.php?23276-Drifting-Skipping-Axis
It seems when I ran them at the...

OMG that single flute Super O bit test I just did is like night and day! I did three 0.75" deep slots:
Top: 1/4" 2 flute upcut at 1.5ips 12k
Middle: 1/4" 2 flute upcut at 1ips 12k
Bottom: 1/4"...

Burkhardt do you know of an easy way in VCarve to do a slot wider than the bit? The only way I could think of is to:
- make a path with a large offset to the first DOC
- repeat that path without...

Thanks guys. I have a single O that I'll give it a try with. I'll admit my dust collection likely leaves a bit to be desired. The CNC is in the house as I didn't fancy leaving it out in the...

Hey y'all! I'm finding that I'm getting pretty poor chip clearance when running profile paths that are more than 1x DOC that are essentially slots. For example cutting out the body shape of a guitar...
