03:36 AM travis_farmer: Morning :-)
04:11 AM Tom_L: morning
04:53 AM JT-Cave: morning
04:58 AM JT-Cave: 66°F
05:46 AM JT-Cave: rooster has crowed
07:17 AM skunkworks[m]: ithe2guu you might want to look at this. It could be an issue with the drive or a setup - but he is having your same problem (no direction change)
07:17 AM skunkworks[m]: https://bbs.homeshopmachinist.net/forum/general/2048770-help-me-understand-this-simple-schematic
07:19 AM skunkworks[m]: he has a new one coming - as the tech gave him some things to follow - and they failed - although others think it is a config problem. I don't know
10:34 AM JT-Shop: https://www.facebook.com/marketplace/item/1397866114443666/?ref=browse_tab&referral_code=marketplace_top_picks&referral_story_type=top_picks
10:34 AM JT-Shop: fixer upper
11:04 AM pcw--home: Needs a little touch-up
11:11 AM JT-Shop: hi pcw--home
11:13 AM pcw--home: Hi JT
11:14 AM JT-Shop: how's it going out there?
11:14 AM pcw--home: OK, still busy redesigning cards
11:14 AM JT-Shop: any new ones on the shelf?
11:16 AM pcw--home: for production, Should have 7I95Ts 7I96S, 5I25Ts and 7I80HDTs soon
11:16 AM JT-Shop: cool, I'm waiting on the 7i96s and prob get a few 7i95ts
11:17 AM pcw--home: no time for new stuff yet except the new versions of 7I84,7I76E,7I76,7I77
11:17 AM JT-Shop: what's new on the 7i76 and 7i77?
11:18 AM pcw--home: New output drivers (support sourcing,sinking or push-pull outputs and no flyback diodes required)
11:19 AM JT-Shop: nice
11:19 AM travis_farmer: sounds like it would be good for small relays
11:19 AM pcw--home: also 7I76/7I76E spindle output supports ENA/DIR and FWD/REV
11:20 AM JT-Shop: wow that's cool
11:20 AM pcw--home: Yeah not needed flybacks is nice. Also current per output is 500 mA instead of 350 mA
11:20 AM travis_farmer: :-)
11:20 AM JT-Shop: just keeps getting better :)
11:22 AM travis_farmer: now if only you could create a spindle VFD that supported most spindles, and only needed a SSerial connection ;-)
11:23 AM pcw--home: Well... modbus is _just_ now supported by Mesa FPGA cards (Thanks Andy!)
11:24 AM JT-Shop: and better :)
11:24 AM JT-Shop: thanks andypugh
11:25 AM JT-Shop: cool down done... time for a nap
11:25 AM travis_farmer: modbus on mine is only 80% reliable. (mb2hal), i may be going back to analog control with modbus readout, if it supports it on the VFD...
11:43 AM roguish[m]: JT-Shop: good morning. hey, why did you pick those particular Jabra
11:43 AM roguish[m]: aids
11:43 AM roguish[m]: just curious. I gotta shopping for some too
11:54 AM perry_j1987: looking to build a new control cabinet for this little taig mill. do you guys have any suggestions other than these junction boxes im looking at
11:55 AM Tom_L: i used a regular industrial box on mine
11:56 AM Tom_L: used on ebay for $75ish
11:56 AM travis_farmer: i used a small-ish wall-hung server/switch rack enclosure... and i think i regret it... almost
11:57 AM roycroft: i have several industrial boxes that i've picked up over the years, but none are the right size for my control cabinet for the cnc router
11:57 AM roycroft: i'm just going to make one out of baltic birch plywood or mdf
11:57 AM perry_j1987: got a link to "industrial box" lol rubber gloves comes up when i search that term in ebay lol
11:58 AM travis_farmer: try "industrial enclosure" maybe
11:58 AM roycroft: maybe i'll line the box with copper to help contain the noise
11:58 AM Tom_L: https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=rittal+industrial+box&_sacat=0&LH_TitleDesc=0&_osacat=0&_odkw=regal+industrial+box
12:01 PM Tom_L: https://www.ebay.com/itm/256055588320 that's the size of mine although that one is new
12:02 PM Tom_L: err maybe not...
12:02 PM perry_j1987: how is the depth on that 8.5
12:02 PM Tom_L: ignore my messy wiring: http://tom-itx.no-ip.biz:81/~webpage/rue/Control2.jpg
12:03 PM Tom_L: it all fits
12:03 PM Unterhaus_: someone on fb asked how to get rid of baby groundhogs and posted a pic. It was a baby bunny
12:03 PM Tom_L: stepper drivers are on the door behind the heatsink
12:03 PM perry_j1987: whats that on the bottom with the caps
12:04 PM Tom_L: analog psu
12:04 PM Tom_L: surplus stuff
12:04 PM Tom_L: one would have been sufficient i think
12:04 PM roguish[m]: perry_j1987: https://www.amazon.com/gp/product/B073RJNDSW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
12:04 PM roguish[m]: lots of room, and not to pricey
12:05 PM Unterhaus_: Tom, your caps are about to implode
12:05 PM Unterhaus_: I suppose that's better than the ones that puff up
12:06 PM perry_j1987: i was looking at this one https://amzn.to/3qdJoKR
12:08 PM Tom_L: kinda small to get it all in there
12:09 PM perry_j1987: i got it in cad i can fit a psu and 4 stepper drivers and the parport card in there
12:09 PM Tom_L: with good cooling circulation?
12:10 PM Tom_L: got a fan on the side?
12:11 PM perry_j1987: fan on bottom blowing up etc
12:11 PM perry_j1987: https://pasteboard.co/TRa4H0ncEpSI.png
12:12 PM Tom_L: long as you can make it work
12:19 PM perry_j1987: i have quite a few 24v psu laying around here
12:19 PM perry_j1987: how big of a difference is it going to 36 or 48
12:21 PM travis_farmer: just remember, just because it all fits, doesn't mean it will be easy to work on, and debug.
12:24 PM perry_j1987: aye
