  1. Re: Do I need a BOB if you use ESS Smooth stepper and Gecko G540

    No, the ESS precludes the need for a breakout board. The only reason you may want one is if you need more than the four inputs and two outputs on the G540, in which case you will want a BOB as a...

    Re: Reversing direction causes motors to jerk

    Hopefully that will get you squared away. I always prefer to err on the side of caution, and this should get you back up and running quickly if the drive is indeed causing the problem.
  3. Re: Z Axis Voltage Adjustment to correct drift on G540

    bcurrey,

    You can run those motors without the 3.48K resistor on the DB9 connector. It sounds like your motor is losing torque when the drive goes into standby mode where it cuts power to 70% of...

    Re: Reversing direction causes motors to jerk

    Despontene,

    How old are your GR214Vs? We have seen some scenarios with a current spike on direction change with the GR214V with certain motor and power supply matchups. This is with the newer...

    Re: replaced pc estop doesnt function.

    Where is the E-Stop issue? Is this the reset button in Mach3 or the physical E-Stop across pins 10 and 12 on the G540? If it is the computer then go ahead and toggle it while measuring the pin on the...

    Re: Gecko g540 ground pin burned out

    The most likely cause of a burned connector on the GND pin is a loose connection. The increased resistance from an incomplete connection on the header can lead to heating on the connector. I'd...
  7. Re: Need help mach 3 and g540 Chinese VFD xyz will not move

    WEBB,

    Are you using our XML file to setup Mach3? If so, can you take a screenshot of your PORTS AND PINS section of the CONFIG dropdown?

    Re: G213V vs GR214V

    Harry,

    Sorry for missing your original post. The GR214V will be the drive of choice for newer applications and will be much more rugged than the already bulletproof G213V. If you ever run into an...

    Re: Help - servos not working.

    The problem sounds like it may be an encoder issue. If you remove a motor from the machine and bench test it does it continue to show a FAULT state at all times? You will need to reset the drives on...
  10. Re: BLDC HX-WS400 connected to GECKO G540 & Mach3

    Sorry for the delay in getting back to you. Can you remove the other electronics entirely and connect a 9V battery across VFD GND and VFD IN? You will then need to repeat the same test and measure...
  11. Re: BLDC HX-WS400 connected to GECKO G540 & Mach3

    Can you measure the voltage out of the G540 across VFD GND and VFD OUT while you change commanded speeds? Lets see what you are actually sending the drive and if it is what it needs.
  12. Re: BLDC HX-WS400 connected to GECKO G540 & Mach3

    Unless I am reading it wrong, this drive is a standalone motor control that takes a STEP and DIRECTION signal. It looks like they call the STEP input "PWM" and DIRECTION input "F/R", which I assume...

    Re: Y axis not repeating

    Can you try swapping motors around so a different axis is controlling the X and Y? You will need to change your pins in Mach4 as well. I want to see if the problem stays on the Y axis or if it tracks...
  14. Re: Geckodrive Thanksgiving Sale 2018 and New Product Line Announcement

    I cannot speak for them but it was discussed as being an option in the future for the ESS. I'd stay tuned because there are some pretty cool things going on with the ESS.

    Since my last post we...
  15. Re: Geckodrive Thanksgiving Sale 2018 and New Product Line Announcement

    Initially the GR570 will be ESS only, and that will be our preferred way of controlling it. We plan on having several different motherboards that accommodate other motion controllers like the UC300...
  16. Re: Geckodrive Thanksgiving Sale 2018 and New Product Line Announcement

    So for your NEMA 34 you have a maximum voltage of 92VDC that can go through it before it no longer has a linear relationship with power and heating. You can run those motors at 50VDC without issue...
  17. Re: Geckodrive Thanksgiving Sale 2018 and New Product Line Announcement

    In that case it sounds like the GR570 would not have the voltage you need, so the GR204V would likely be the best bet for you. There is a bit of a misnomer with steppers and the inductance formula...

    Re: Difference between G320 (legacy) and G320X

    Roger,

    That is one hundred percent correct. The HEDS can be used if you put a line driver on there, but those CUI encoders are so cheap it is often not worth the hassle to track down or build a...

    Re: Difference between G320 (legacy) and G320X

    Hey, sorry for missing this when it was posted. The G320X is designed to be a drop in replacement for the G320 with one caveat: its encode failure detection may trip with older encoders (mainly HEDS...

    Re: G540 ground questions

    The case of the G540 should be grounded to DC(-) already through the mounting screws on each G250XR3 inside. It never hurts to be double sure you ground everything, but that wire may not be necessary.

    Re: Geckodrive: Back to Basics and Price Drops

    Harry,

    Well, the G540 is de-rated to 50VDC so that would likely not damage anything. The drop dead voltage is closer to 60VDC so if your 56VDC is clean (with 0% ripple), something a battery...

    Re: GR252 and the New Raptor Series of Drives

    ger21,

    Gotcha. The G214 already has an adjustable standby current through its T2 trimpot, and the GR214 will retain that feature.

    The GR252 project is coming together pretty quickly and we are...

    Re: GR252 and the New Raptor Series of Drives

    jfong,

    The reason the Trinamic chips are running quietly is likely due to a high microstep resolution; the GR252 will go up to 256 microstep so it will run very quietly at low speed. We will be...
