Quite an Unusual one

[JAZZCNC]

Its unbelievable how poor the choice of BOB is today. Couldn't be that more clear what is needed:

-USB or Ethernet board,small sized, mach3 plugin, on board spindle control, on board 220AC/transformer, opto isolated inputs and outputs, 6-8 axis,4 relays,...

Combining all of these is almost impossible and starts to get expensive. Same price as second hand motion controller

If you don't need slaved motors and using steppers then have a look at the Csmio-IP-M controller or the Csmio-IP-S if you need slaved motors or using Servos with high count encoders and want the full package. Here CS-Lab - CSMIO - CNC Ethernet Controllers- inexpensive solutions - CS-Lab CNC controllers CNC Machining CNC software.

They are very high quality Ethernet Motion control units with industry standard 24V differential digital I/O so very good at handling electrical noise also come with very High quality Analogue spindle output built in. (Sorry to say this Eddy but those Spindle 4 boards are very erratic with speeds jumping around all over the place, used a couple now and not impressed.)

No BOB or external Spindle board is needed all mounts on industry Standard Din rail with separate quality Din rail connectors. Simple to fit and install plus very very neat.

I've used just about every Motion control card now in the Diy range so Sub £300 and I can tell you 100% these knock the spots off any other.

I've fitted 2 now but only on new build machines so couldn't compare same machine performance against other Cards but unfortunately and very very frustratingly for ME that's just changed.!!
The Russian PLCM E3P I've been using on my own machine has just gone faulty, doing strange things and tripping with noise issues from VFD, either using USB or Ethernet connections.

Couldn't have happened at worse time has I've been flat out chasing my arse between Family health issues and getting stuff done plus now every where is closed for Xmas. Just lent my spare ESS smooth stepper to a friend who isn't answering his bloody phone, just sold the spare spare USB SS has never used it. . Arghhhh . .(PLCM E3P is now smashed into 1,0000000000000 bits.!!! and NO it gave me no satisfaction other than to vent.!)

No way was I going back to Parallel port, plus laptop doesn't have PP. So I've got Csmio-IP-M which was half fitted into a control box destined for machine currently !!.Trying.!! to finish but needs must so out it came temporarily until I can get another Card.

WOW . . . 20mins later it's wired up, software installed and working with full spindle control.
Worked Straight off Copy of my Old Mach3 profile with just a quick Plug-in swap and pin assignments with very little tweaking of motor tuning required. . . In fact this is what really impressed me has now can tune the motors much higher even thou the PLCM-E3P and CSMIO_IP_M are both supposed to be 100Khz.

I haven't had or got much time to play and don't need the speed anyway but the first dabble took my My Y axis from Max 11mtr/min & 950s/s Accel to stable 14Mtr/min at 1200s/s and that's with 5mm pitch screw direct drive on 3.5Nm Nema 34 motor at 75v. That's 2800Rpm from Nema 34 motor.!!!. . I was quite impressed with 2200rpm the PLCM allowed.!!

The Motors so sound very sweet even at these dizzy heights and the pulses are clearly very smooth has the movement is excellent even at very low feeds.
Wouldn't ever run at that speed has I don't need it but it just shows not all Cards are Equal and I'm positive this speed increase is down to the quality of the product has it's the only thing that has changed on my machine.! . . .Very impressive and I won't be coming off any time soon so I better get another ordered ASAP.

. . . . . HAPPY NEW YEAR EVERYONE. . . .Keep smiling.
