[00:00:01] <Tom_itx> if it's on IO 3..7 it won't work
[00:00:05] <JT-Shop> I don't know what that is
[00:00:13] <Tom_itx> io 3..6
[00:00:20] <Tom_itx> those are the sserial IO
[00:00:26] <Tom_itx> acording to your dmesg
[00:00:29] <JT-Shop> it's connected to the encoder input
[00:01:04] <JT-Shop> I don't know what IO 3..7 is
[00:01:21] <Tom_itx> [ 153.224287] hm2/hm2_5i25.0: IO Pin 003 (P3-15): Smart Serial Interface #0, pin TxData1 (Output)
[00:01:21] <Tom_itx> [ 153.224295] hm2/hm2_5i25.0: IO Pin 004 (P3-03): Smart Serial Interface #0, pin RxData1 (Input)
[00:01:21] <Tom_itx> [ 153.224304] hm2/hm2_5i25.0: IO Pin 005 (P3-16): Smart Serial Interface #0, pin TxData0 (Output)
[00:01:21] <Tom_itx> [ 153.224312] hm2/hm2_5i25.0: IO Pin 006 (P3-04): Smart Serial Interface #0, pin RxData0 (Input)
[00:02:22] <Tom_itx> follow it back to the 5i25 card
[00:02:54] <JT-Shop> I only see a P1 on the 7i77
[00:03:03] <PCW> I think its likely you have a ground loop
[00:03:16] <Tom_itx> well i bet it isn't borked
[00:03:24] <Tom_itx> sry, gotta go for now...
[00:03:46] <JT-Shop> ground loop on the encoder input?
[00:04:15] <PCW> I would disconnect the probe and it s ground and see if things get better
[00:05:45] <PCW> probably encoder ground connected to some noisy machine ground somewhere
[00:06:20] <PCW> (well guessing from x thousand miles away)
[00:06:38] <JT-Shop> hey your guess is better than mine :)
[00:07:00] <JT-Shop> did you say you had a more noise resistant firmware for the 5i25
[00:07:52] <PCW> Working on it
[00:08:21] <PCW> still wont fix big ground loops (need 7I77ISOL or 7I92 for that)
[00:08:23] <JT-Shop> ok
[00:11:12] <PCW> A few people have noticed greater noise sensitivity on newer (V37+) sserial firmware
[00:11:14] <PCW> I suspect it is because the UART base clock runs at 100 MHz instead of 33 MHz so
[00:11:15] <PCW> I am adding a input digital filter to the RX UART
[00:12:05] <PCW> (this will only affect extra character errors from impulse noise)

[00:14:22] <JT-Shop> I ordered a 7i77isol
[00:15:03] <JT-Shop> at least I think I did
[00:17:12] <JT-Shop> gotta run for now, thanks for the help Peter

[19:19:28] <aventtini6> i got a huge wf72ch
[19:19:35] <aventtini6> this week
[19:22:14] <zeeshan> nice
[19:22:57] <zeeshan> im retrofitting a huge deckel fp50cct
[19:23:05] <zeeshan> its huge!
[19:23:09] <aventtini6> its a huge differance on construction
[19:23:13] <aventtini6> i got a wf51
[19:23:18] <aventtini6> a wf31
[19:23:24] <aventtini6> and a wf72
[19:23:32] <aventtini6> from small to the largest one
[19:23:35] <zeeshan> aventtini6: you need to send me an overboard arm for the wf31 :(
[19:23:38] <zeeshan> haha you got all of them
[19:23:40] <zeeshan> so luckly :)
[19:23:53] * archivist grmbls
[19:23:58] <aventtini6> you men the side head moving arm ?
[19:24:02] <zeeshan> no
[19:24:03] <zeeshan> i have that
[19:24:08] <aventtini6> aaa
[19:24:09] <zeeshan> but when your machine is in horizontal mode
[19:24:10] <aventtini6> i know
[19:24:20] <zeeshan> there is an overboard arm that connects from Y axis ram
[19:24:23] <aventtini6> i dont have the at any of them
[19:24:28] <zeeshan> they are rare
[19:24:29] <aventtini6> the wf72
[19:24:40] <aventtini6> has a 1m 4 axis table
[19:25:34] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[19:25:42] <zeeshan> see i wanted a 4 axis table for my machine
[19:25:46] <zeeshan> but the factory one is kind of useless
[19:25:51] <zeeshan> because all it does is rotate..
[19:25:58] <zeeshan> along the C axis
[19:26:04] <zeeshan> which in my opinion is useless..
[19:26:11] <zeeshan> it'd be more useful if it was an A or B axis table
[19:26:15] <zeeshan> (at least for me)
[19:26:43] <FinboySlick> My lazy weekend youtube was rather productive today:

[19:28:10] <aventtini6> yes i know i was thinking of putting the original table
[19:29:37] <aventtini6> im truning to get some 7i77
[19:29:43] <aventtini6> and a 5i25
[19:30:01] <aventtini6> and i see there are not in the online shop as a combo
[19:31:57] <aventtini6> and i see now from 92 up it has Bosch SPM for the spindle and no gears

[19:51:12] <aventtini6> its the old bosch drives

[19:53:53] <zeeshan> but youre limited on speed :/
[19:53:54] <aventtini6> yes it has doable
[19:54:02] <zeeshan> oh
[19:54:05] <zeeshan> its glass scale + encoder ?

[19:54:10] <zeeshan> wow nice!
[19:54:13] <zeeshan> thats awesome
[19:54:19] <zeeshan> i bet it uses the encoder for commutation

[22:11:19] -!- anth0ny_ has quit [Quit: anth0ny_]
[22:11:56] <PCW> likely a ground loop between the analog out (servo drive ground) and the PC
[22:12:39] <PCW> do the drives have differential inputs? (in+ and in-)
[22:13:42] <PCW> also did you do a full power cycle? (reboot wont work)
[22:16:03] <JT-Shop> yes full power cycle, funny thing the spindle works and it has encoder feedback
[22:17:37] <JT-Shop> the drives have two wires for +-10v
[22:18:43] <PCW> are they labeled something like AIN+ and AIN- or is one ground?
[22:19:02] <JT-Shop> let me see if I can see a label
[22:23:35] <JT-Shop> the sheild and the black wire go through a small resistor you had me to add a long time ago then to GND on TB5 and the red wire goes to AOUT0, no labels on the drive
[22:24:19] <PCW> do all channels have a resistor?
[22:25:38] <JT-Shop> only the three axes
[22:26:15] <JT-Shop> well that is all the drives I have
[22:26:24] <JT-Shop> the spindle is run by modbus
[22:28:29] <PCW> trying to make sure no 7I77 ground lead connects directly to frame ground at the 7I77 end
[22:28:31] <PCW> those errors mean that enough high frequency current is flowing in the DB25 cable that there is a greater than 1.4V drop
[22:28:32] <PCW> so the 5I25 end sees characters that are not there (even with the added 200 ns filter)
[22:29:06] <PCW> (1.4v drop from end to end)

[22:33:26] -!- distrozapper has quit [Ping timeout: 240 seconds]
[22:34:10] <PCW> The trick is to make the path impedance higher so the ground current through the DB25 cable is minimized
[22:34:12] <PCW> Where the PC is plugged in makes a difference. Also the DB 25 cable should be kept away from power lines

[23:07:45] <JT-Shop> no, I disconnected the shield from the analog out and now it works
[23:08:29] <PCW> fixed the sserial errors?

[23:09:03] -!- anth0ny_ has quit [Client Quit]
[23:10:06] <JT-Shop> when the sserial errors come there is a bunch then axis following error
[23:10:44] <PCW> are the encoder cables shielded?
[23:10:46] <PCW> if connected at both ends this is a way to channel ground from the motor through the DB25 cable
[23:10:58] <PCW> channel ground noise
[23:13:24] <JT-Shop> the encoder cables are shielded and grounded at the entrance to the cabinet so in the middle of the cables
[23:14:18] <PCW> and the shield is not connected at the 7I77 end?
[23:14:22] <JT-Shop> let me look at the encoder end of the cable, the 7i77 end the shield is not brought out
[23:15:04] <PCW> if its not connected at the 7I77 end, that should be OK
[23:17:45] <PCW> one easy way to check grounding is to power down, disconnect the DB25 cable and measure from 7I77 GND (say TB1 pin1)
[23:17:46] <PCW> to servo cabinet ground
[23:18:44] <PCW> does the DB25 cable go through a panel (where the shell might be grounded to the servo cabinet) ?
[23:21:41] <JT-Shop> no, the only thing is is touching is the back of the PC
[23:22:34] <JT-Shop> the 170vdc power supply is a bridge rectifier, a large blue capacitor with a power resistor across the terminals, could that be a source of the problem?
[23:24:33] <PCW> Its most likely high frequency noise from the servo drive getting into the DB-25 cable
[23:27:41] <os1r1s> PCW Do you know if 7i77's are in stock to ship?
[23:27:47] <JT-Shop> the drive power and encoder cable run though the same flex conduit with mill speck connectors on each end
[23:28:34] <PCW> we have sonme 7I77s but I think they are all allocated to dealers
[23:29:19] <PCW> what powers the 7I77 5V?
[23:30:02] <JT-Shop> a 5v power supply... I wonder if the left over wire laying on one terminal of the 170vdc power supply could be the problem
[23:30:44] <JT-Shop> nope
[23:31:26] <PCW> Is the 5V supply floating? (a PC power supply would be an issue here since common is frame ground)
[23:33:13] <JT-Shop> the power supply is grounded, not sure about the DC out
[23:34:41] <PCW> I would try the ohmmeter check (7I77 GND to servo cabinet frame ground with DB 25 disconnected)
[23:35:02] <JT-Shop> the 5v power supply 0v is grounded, the 24v power supply the 0v is floating
[23:35:05] <JT-Shop> checking
[23:35:47] <PCW> I would disconnect the 5V common from ground
[23:37:20] <JT-Shop> TB1 pin 1 shows 5 ohm to frame
