01:38 AM Deejay: moin
04:24 AM Tom_L: morning
05:48 AM JT-Cave: morning
07:06 AM JT-Cave: rooster finally crowed
07:25 AM Tom_L: 51F
07:37 AM JT-Cave: 64°F low 50°F
07:37 AM JT-Cave: and no heat
07:44 AM Tom_L: thought you just replaced that
07:55 AM JT-Cave: he thinks it's a bad gas valve... all systems work except no gas comes out when the valve clicks
08:06 AM * JT-Cave tries to solve a coding puzzle before starting his chicken day
08:22 AM JT-Cave: one puzzle solved time to start my chicken day
09:59 AM Tom_L: JT-Cave, pilot lit?
10:01 AM Tom_L: ran into a safety switch on the niece's water heater that had to be reset before the pilot would stay lit
11:04 AM JT-Shop: Tom_L, none
11:07 AM Tom_L: piezo pilot?
11:14 AM JT-Cave: no pilot at all
11:16 AM JT-Cave: fan comes on for a bit then the exhaust blower for a bit then the igniter glows white hot then the gas valve clicks but no gas comes out
11:16 AM Tom_L: mmm
11:16 AM JT-Cave: that's what I said
11:16 AM Tom_L: poor quality control
11:16 AM travis_farmer: somebody steal your gas while you were away?
11:17 AM JT-Cave: nope
11:18 AM Tom_L: i would think something like a gas valve would get checked 100%
11:19 AM travis_farmer: and you didn't turn off any isolation valves?
11:20 AM JT-Cave: I checked for gas at the heater
11:21 AM JT-Cave: going to go over the LP conversion instructions after while to see if he missed a step
11:22 AM Tom_L: good to find out now instead of the dead of winter
11:22 AM travis_farmer: true
11:22 AM JT-Cave: and hook up my man-o-meter to verify the gas pressure
11:22 AM Tom_L: i got a test gage stashed away somewhere
11:23 AM Tom_L: but that's for new plumbing
11:23 AM * travis_farmer needs to get the RV furnace put back into old shop before winter...
11:23 AM JT-Cave: I have a pressure gauge for testing for leaks
11:24 AM JT-Cave: we have some 39-43f nights coming up this weekend
11:24 AM travis_farmer: been that here
11:24 AM Tom_L: sleep with the chickens
11:25 AM Tom_L: i'm sure ours isn't far behind
11:25 AM Tom_L: getting cooler here
11:25 AM JT-Cave: they are pretty warm with normal temp of 106°F
11:26 AM CaptHindsight: "sleep with the chickens" is that what the mob has come to now days?
11:26 AM travis_farmer: lol
11:27 AM Tom_L: i got a radient heater in the basement for emergencies if power goes out
11:27 AM travis_farmer: house furnaces are hooked up to standby generator here
11:28 AM Tom_L: that's a 2nd option
11:28 AM travis_farmer: and if oil runs out, we have a wood furnace
11:29 AM JT-Cave: I have several oil filled heaters and will use them upstairs and down here
11:32 AM travis_farmer: i haven't even visited my machine in days... been too busy with other pre-winter projects
11:33 AM JT-Cave: got the snow plow mounted yet?
11:33 AM Tom_L: put a new belt on my blower earlier
11:33 AM Tom_L: probably won't need that for a while
11:33 AM travis_farmer: not yet, maybe this weekend
11:35 AM travis_farmer: not sure when the last mowing day will be...
11:37 AM Tom_L: JT-Cave, made enough changes to build yet?
11:39 AM JT-Cave: let me test on the bp and see if it makes a working configuration or not
11:39 AM JT-Cave: but first there seems to be a nap in my near future
12:08 PM * travis_farmer heads out to attempt tool probing again...
12:55 PM * JT-Shop is unsure why you need to probe anything on a router
01:00 PM travis_farmer: so i can get my tool length, and maintain correct offset between tool changes
01:01 PM roycroft: yeah, folks touch off for z all the time on routers
01:01 PM travis_farmer: whatever the case, i am doing it wrong...
01:04 PM roycroft: well do it right then
01:05 PM roycroft: you already know how not to do it
01:05 PM roycroft: that should make it easier to figure out the right way
01:05 PM travis_farmer: if i knew what i was doing wrong...
01:08 PM JT-Shop: I find a steel dowel to be very accurate, simple and mistake proof
01:09 PM travis_farmer: i am updating my forum post with my exact method, perhaps somebody can point out where the flaw is...
01:11 PM JT-Shop: chris's probe routines are bullet proof and work
01:12 PM travis_farmer: people keep telling me that, but if i don't figure out what is wrong with mine, i won't learn anything... ;-)
01:20 PM JT-Shop: that's true...
01:24 PM travis_farmer: https://forum.linuxcnc.org/40-subroutines-and-ngcgui/50139-my-calculations-are-off-aparently-need-help-with-spacial-math#282921
01:29 PM travis_farmer: i may have thought of my flaw, but i will wait and see if that is what is pointed out... basing my theory on JT's dowel...
01:30 PM JT-Shop: you need to see a video of that method?
01:31 PM travis_farmer: i think me using random tools to touch off with is wrong...
01:31 PM JT-Shop: well if you don't know their diameter it is wrong to use them
01:31 PM JT-Shop: https://www.youtube.com/watch?v=VmRUJk0ptN4
01:31 PM roycroft: diameter doesn't matter if you're only touching off z
01:32 PM JT-Shop: diameter of the dowel
01:32 PM roycroft: yeah
01:32 PM JT-Shop: not the cutting tool
01:32 PM roycroft: oh, wait
01:32 PM travis_farmer: and basing my touch-offs on my spindle nose is wrong. i need a steel dowel to base all my offsets from, not my spindle nose
01:32 PM roycroft: yeah, you would not touch off z with a dowel
01:32 PM roycroft: unless you were intending to machine with said dowel
01:32 PM JT-Shop: what?
01:32 PM JT-Shop: think about that...
01:32 PM roycroft: unless you have the tormach tool system
01:33 PM JT-Shop: not needed
01:33 PM JT-Shop: look at the axis touch off popup
01:33 PM roycroft: the dowel would be for x/y indexing
01:33 PM roycroft: the spindle nose would be for z, if anything
01:34 PM JT-Shop: I use a dowel in the spindle for x and the back of the vise is Y
01:34 PM travis_farmer: i assumed the touch off popup was for touching off without a electronic tool probe
01:34 PM JT-Shop: yup
01:35 PM JT-Shop: so like the video shows you touch off to either the material top if you don't have repeatable tools or a known surface if you do
01:35 PM JT-Shop: if you have repeatable tools you only need to touch off using the down one tool to the material top
01:35 PM * JT-Shop wanders down to the beer cave to see why analogena is using port 4
01:36 PM travis_farmer: my tools stay in the holders, so i assume they repeat
01:37 PM JT-Shop: well once you verify your tools repeat for z then you can touch off all the tools z to a fixed surface
01:37 PM JT-Shop: then you can take a tool and touch off to material and the rest will be set
01:37 PM travis_farmer: my tool sensor
01:38 PM travis_farmer: for fixed surface
01:38 PM JT-Shop: that would work
01:38 PM JT-Shop: you have a cat or bt type of spindle?
01:38 PM travis_farmer: BT30/ISO30
01:39 PM travis_farmer: but when i change tools, my material to tool tip is no longer zero
01:45 PM JT-Cave: most likely it's either your not setting the tool table correctly or your not loading the tool offset when you change the tool
01:46 PM travis_farmer: so i have to G43 after every tool change?
01:47 PM travis_farmer: i guess i assumed LCNC did that automaticly... :-/
01:50 PM travis_farmer: just checked my toolchange routine, there is a G43 after changes
01:54 PM travis_farmer: my guess is the numbers i am getting from the probe routine i have are wrong, because i enter them like that into the tool-db
01:57 PM travis_farmer: for example, my tool 1 is "T1 P1 Z-2.601 D0.125" in the tool table
01:58 PM travis_farmer: T2 P2 Z-1.1730 D0.25
01:58 PM travis_farmer: and so on...
02:01 PM JT-Cave: never assume
02:01 PM * JT-Cave finally got the chickens sorted out for the day
02:02 PM JT-Cave: what G code do you do to touch off to fixed surface?
02:02 PM travis_farmer: https://github.com/travis-farmer/linuxcnc/blob/master/nc_files/probe-print.ngc is where i get my numbers from
02:03 PM JT-Cave: do you know what is in there?
02:04 PM JT-Cave: seems hugely complicated to just touch off with
02:05 PM travis_farmer: some of it is copied from a routine Funkenjaeger wrote
02:05 PM travis_farmer: line 23 is where the routine starts
02:06 PM JT-Shop: I'd start from scratch especially if something you copied does not work and you don't understand everything about it
02:09 PM travis_farmer: it just uses G59.3 as freespace to probe in, like a blank piece of paper
02:09 PM travis_farmer: that way the set work offsets don't screw it up... unles i use G59.3 for something
02:12 PM travis_farmer: then i probe down at a slow pace to find the tool sensor, than back-probe until the probe clears. then i probe and back-probe again at a much slower pace for accuracy
02:13 PM -!- #linuxcnc mode set to +v by ChanServ
02:16 PM JT-Shop: well finally getting my pins for the 6i25/7i77 :)
02:16 PM rmu: this g59.3 as probe wcs isn't necessary, you can always use G53 G0 X... to go to your absolute probe position
02:18 PM -!- #linuxcnc mode set to +v by ChanServ
02:20 PM travis_farmer: maybe i should just sell my machine for $1... seems i am far too dumb to ever know how to use it... :-(
02:30 PM * roycroft suspects travis_farmer will figure it out
02:36 PM rmu: travis_farmer: i replied with example that should work (not out of the box, but you will get the picture), adapted from probe basic
02:37 PM rmu: i think i removed assumptions about g59.3 and a fews other things
02:42 PM JT-Shop: hmm the encoder counts so making progress
02:42 PM * JT-Shop wonders why people try and do the most complicated thing first?
02:43 PM * Tom_L just wonders
02:46 PM * JT-Shop sets a groundhog trap
02:46 PM XXCoder: https://youtu.be/ZcwkLN1SDTA restoring classic car wood steering wheel
02:47 PM Tom_L: JT-Shop, the bill murray way?
02:48 PM JT-Shop: lol
02:48 PM JT-Shop: no, with melon guts
03:07 PM * JT-Shop "thinks" he figured out what is missing for the 5i25/7i77 configuration
03:26 PM roycroft: depends on how cold it is
03:26 PM XXCoder: true. theres that ice hotel
03:33 PM * roycroft will go dig out the mesa hardware after work
03:48 PM Tom_L: JT-Shop, you have a 5i25 on the BP?
03:52 PM JT-Shop: yup
04:15 PM Unterhaus_ is now known as Unterhausen
04:16 PM Unterhausen: I just did a test and I'm pretty sure my drill press vise is crooked.
04:16 PM Unterhausen: I suppose I should check the tram of the table to make sure
04:16 PM Unterhausen: no idea how to fix a vise
04:17 PM JT-Shop: I use an edge finder to set the back jaw of the vise
04:20 PM Unterhausen: the problem is it's not trammed.
04:20 PM Unterhausen: vertically
04:21 PM Unterhausen: It's a Palmgren 30301, $1000, so it should be closer than it is
04:25 PM Unterhausen: I'm not sure I can trust someone with a tiny benchtop drill press to tell me how to check it for square
04:26 PM Unterhausen: I'm a drill press snob, apparently
04:46 PM Unterhaus_ is now known as Unterhausen
04:47 PM Unterhausen: I think the moral of the story is I should have leveled the drill press a long time ago
05:05 PM JT-Shop: I missed the drill press part...
06:59 PM Unterhausen: squaring up the drill press isn't going well, going to have to wait until I have more patience
07:20 PM CaptHindsight: https://www.ajaxtoolsupply.com/pa3x3x1crslv.html
07:22 PM CaptHindsight: https://www.ajaxtoolsupply.com/br9x48tavemi.html look at the BP versions and prices
09:35 PM Unterhausen: it's never a bug, thanks for playing
09:36 PM Unterhausen: that bp page is weird, you can select your price
09:38 PM Unterhausen: I selected all the prices and then it wouldn't add it to my cart, too much money
09:38 PM roycroft: what some call bugs others call adventures
09:43 PM Unterhausen: there are bugs in lcnc, but not loading files. Someone just didn't look in the right directory
09:44 PM Unterhausen: it helps if you name your files with different names
