12:27 AM Bleepshop: _unreal_: My original/current Z riser plates are 0.75" and I've got ~2" of travel out of a possible 5" on tee rails. I need to find a 12x36 slab to cut a new set from the will raise the Z by 6" so I can move the spindle back down on the mount and still have 4-1/2" of Z.
12:35 AM Bleepshop: s/tee/the
12:35 AM Bleepshop: That's 0.75" 6061-T651 by the way.
02:07 AM Deejay: moin
05:50 AM Tom_L: morning
07:13 AM mrec_: can anyone recommend a parallel port switch?
07:13 AM _unreal_: switch?
07:13 AM _unreal_: what do you need to do with it. there are different types
07:13 AM mrec_: I have a lathe and a cnc mill both controlled mostly via parallel port
07:13 AM _unreal_: OH.. direct control
07:14 AM mrec_: currently I use to switch the cable but that's not really comfortable
07:14 AM _unreal_: then I would get an A:B manual rotary switch
07:14 AM mrec_: do you have one?
07:14 AM _unreal_: dont get a digital one
07:15 AM _unreal_: :S likely but I dont know where.
07:15 AM mrec_: maybe that's some idea..
07:15 AM mrec_: FPGA + some level shifters
07:15 AM mrec_: I still have lots of pins free on my stm32 usb port
07:16 AM _unreal_: You want something like this https://www.cablewholesale.com/products/computer-products/switch-boxes/product-40d3-17602.php
07:16 AM _unreal_: I said DONT get a digital switch box
07:17 AM _unreal_: you risk introducing delays
07:19 AM mrec_: I know but if I use an FPGA the delay will not be significant
07:19 AM _unreal_: A: that would be a lot of work to MAKE a switch B: your risking introducing delays into the par signal. C: you can get one of these boxes for next to nothing on ebay, or get one from amazon or some location on the internet
07:19 AM mrec_: I still have some ice40hx boards here
07:20 AM _unreal_: your call. but that would be a lot of work, lot of coding.
07:20 AM mrec_: not really
07:20 AM _unreal_: and there ARE digital switch boxes out there all ready. they just have a push button.
07:20 AM mrec_: I've done quite some FPGA work in the past
07:21 AM _unreal_: how is your STM32 coding?
07:21 AM mrec_: the stm32 is just controlling and interfacing the spindle
07:21 AM mrec_: https://weiss-machines.com/en/produit/fraiseuse-detabli-vm18l/
07:21 AM _unreal_: how is your STM32 coding/compiling skills??
07:21 AM mrec_: no problem at all
07:22 AM _unreal_: I have one simple issue
07:22 AM _unreal_: I need GRBL compiled for STM32 black pill
07:24 AM _unreal_: with a few features from grbl github added to the compile. its for my laser etcher. I just need to upgrade the the controller from arduino to a nice 32 bit
07:25 AM _unreal_: If your going to compile, FPGA would be a nice way to go about it.
07:25 AM _unreal_: hello?
07:28 AM jdh: get another parallel port. cheaper and no switching required.
07:34 AM _unreal_: mrec_, hello?
08:04 AM mrec_: sorry had to read a story for my daughter.
08:04 AM mrec_: no I'm using linuxcnc here not grbl
08:04 AM mrec_: I used grbl for another mill a long time ago.
08:04 AM _unreal_: mrec_, I....... need help
08:05 AM mrec_: the pci/pci-e ports of the mainboard are occupied already unfortunately
08:06 AM mrec_: fpga with some gpio switcher interface should be okay
08:07 AM _unreal_: mrec_, I'm asking would you be able/willing to compile the current version of GRBL32. I just dont have the ablity to compile it.
08:08 AM _unreal_: Nor the know how.
08:08 AM _unreal_: pissis me off no one publishes the HEX files.
08:10 AM _unreal_: mrec_, what will make that easy for you. is all the I/O are hard set as output or input. No bidirectional coding needed
08:32 AM mrec_: last time I compiled grbl was a long time ago it's not so difficult just search for some online documentation
08:32 AM mrec_: there are different build systems out there for different projects
08:32 AM mrec_: https://beltrani.com/building-and-installing-grbl-from-source/
08:33 AM mrec_: for example this one
09:33 AM robinsz: afternoon
09:33 AM robinsz: so, my current nightmare is getting files to/from linux cnc
09:34 AM robinsz: I can see the machine over SMB, with "homes" as a published share
09:34 AM robinsz: attempting to navigate to that though fails
09:35 AM robinsz: restarting smbd doesn't seem to help
09:42 AM robinsz: are there any good, reliable methods for getting files to/from the machine that you recommend, other than a memory stick!
09:43 AM mrec_: winscp?
09:43 AM mrec_: I'm using scp
09:43 AM mrec_: on macos
10:18 AM roycroft: are you still about, robinsz?
11:00 AM pcw---home: JT-Cave: found a 7I76E and 7I96 for testing, will send Monday
11:07 AM robinsz: mrec_, good idea! thankyou!!
11:08 AM robinsz: quite why samba is not playing I have no idea
11:09 AM mrec_: samba is soso there are some incompatibilities sometimes
11:10 AM mrec_: I also saw that with our synology NAS
11:10 AM mrec_: but we aren't using SMB too much here
11:12 AM robinsz: its a crappy protocol that never works at the best of times
11:12 AM mrec_: probably also depends which system you use with it
11:12 AM mrec_: which windows
11:13 AM mrec_: last time I used it for saving some altium electronic design files it was okay
11:30 AM roycroft: i use smb for sharing with windows on my nas, but i use nfs for mac os and linux
11:30 AM roycroft: but i found the smb shares a little flaky
11:31 AM roycroft: i finally ended up installing nextcloud on a vm, with the data storage on the nas, and installed the nextcloud client on all my workstations
11:31 AM roycroft: it automatically syncs them all, but there is a slight delay - up to 5 minutes at times
11:31 AM roycroft: it's rock solid, though
11:32 AM roycroft: and had the advantage that files never need to be copied - they just show up on all the machines
11:33 AM roycroft: on the new dedicated windows machine that i just set up for cad work, i didn't even bother with the smb shares - i just installed nextcloud and use that
11:36 AM jdh: I have an smb share on my router. sharing works fine from linux and windows.
11:48 AM roycroft: if it works for you then great
11:48 AM roycroft: i don't know exactly what robinsz is trying to do
11:50 AM roycroft: but if it's creating a smb share on a windows machine and being able to access the files on the linuxcnc machine, "apt install cifs-utils smbclient" will install the samba support utilities on the lcnc machine
11:50 AM roycroft: and then the share can be added to /etc/fstab, and it will automount at boot
11:53 AM roycroft: if it's the other way around, i don't know offhand how to debug it, as i don't do windows stuff much
11:53 AM roycroft: but i know people do it and it works for them
11:54 AM _unreal_: robinsz, what are you using to send files TO the lcnc machine?
11:54 AM _unreal_: an other linux machine or win10?
11:54 AM _unreal_: or mac
11:55 AM _unreal_: robinsz, ?
12:07 PM Contract_Pilot: Miserable 3 days..
12:08 PM Contract_Pilot: Be sure to check you PPE is suited for 254NM if not 120 or so hotus later ya gonna feel it.
12:08 PM Contract_Pilot: 12 or so not 120
12:19 PM JT-Cave: pcw---home, thanks a million
12:46 PM perry_j1987: mornin
12:46 PM perry_j1987: err... afternoon
01:21 PM robinsz: mrec_, win7,
01:23 PM robinsz: mrec_, but don't worry about it, scp gets the job done.
01:52 PM XXCoder: https://youtu.be/7ihitU-EWPY
01:52 PM XXCoder: love this video so far
01:52 PM XXCoder: interesting idea on steady rest with clearance issues
03:13 PM JT-Shop: someone ordered 5 7i92's, 2 7i92m's and a 7i92h along with a few other cards and paypal has a hold on it... I'm not sure why anyone would need that many 7i92's
03:17 PM roycroft: perhaps a maker space building multiple machines?
03:22 PM XXCoder: wow
03:24 PM perry_j1987: maybe they are TERRIBLE with figuring out polarity when wiring up stuff
03:24 PM perry_j1987: lol so they are planning ahead
03:27 PM unterhausen: XXCoder, I managed to bend the bed on my printer, oops
03:27 PM XXCoder: ow what happened?
03:28 PM unterhausen: something was really stuck
03:28 PM XXCoder: not sure how repairable that is
03:28 PM unterhausen: probably can, I'm replacing it
03:29 PM unterhausen: I needed to take it apart before the wires got messed up
03:29 PM unterhausen: I got a glass plate, a mosfet and a heating pad
03:29 PM XXCoder: cool :)
03:30 PM unterhausen: hopefully I can fake the rest
03:31 PM unterhausen: maybe I should have just gotten the gigdigit extended bed
03:31 PM unterhausen: I just didn't want to double the price of my printer
03:33 PM unterhausen: mostly I just can't print at the edge of the envelope of the printer
03:53 PM JT-Shop: I found out why the drivers side outside mirror wound not move on the C5... it wasn't plugged in and some jackleg had been in there doing something in the past

05:19 PM unreal: ok.... that was a long work day
05:20 PM unreal: just finished one of the last things for my sail for my sailboat
05:20 PM unreal: also fixed a bunch of fail(ing)(ed) attachment clips grabbers etc.. hardware.
05:21 PM unreal: tonight I need to make a
05:21 PM unreal: an
05:21 PM unreal: adapter for the wind indicator.. because the sail frame was totally rebuilt. I no longer have a sail indicator
05:22 PM unreal: so I dont have a good indicator of the wind direction :/
05:22 PM unreal: cant wait to take it out
05:22 PM unreal: I may take it out tomorrow
05:22 PM unreal: could have today if I had not had so many things to do. I also did a HUGE washing on the boat
05:22 PM unreal: that took a while
05:22 PM unreal: well bbiab making a beer run
