Question #: 121

Question: when jogging the x-axis, it vibrates

Current Solution

Try increasing the acceleration to accelerate faster and decelerate slower so it passes the resonant frequency more quickly.

  • When I run a file with a lot of z movements, the Z seems to get lower

    Sounds like it is stalling as the z is trying to move up. I would first try putting 3-in-1 oil on the screw and run the z up and down a lot as fast as possible so you can confirm the z is capable again. It could also be the shaft or the lead screw slipping in the coupling. Finally, check the wiring where there may be zip ties or other places where the wires are fastened and look for chafing. This can cause intermittent shorts in the wires.

  • When using the laser controller, what does "engrave beyond border limit" mean?

    LaserCAD: Engrave beyond border limit.

    This is caused by a sweeping motion that is too fast and where the acceleration is too slow. My recommended action would be to keep the acceleration the way it is and slow down the speed of the engrave sweeping motion. I typically use around 200-300 mm/sec and make sure that the axis sweep motion is the nozzle along the gantry, not the gantry itself. The gantry will have too much inertia to sweep, but the nozzle is very light and can sweep very quickly.

    Specifically, what is happening with the engrave beyond border limit is where that axis is not able to slow down fast enough to not hit the border. For instance, imagine a car going 100 mph and it needs to stop within 30 feet. This would not be possible because the deceleration is not high enough.

  • When will the 2.2kw 110v inverter be in stock?

    It's actually difficult to say when we will get our 2.2kW 110v VFDs (Variable Frequency Drives) in stock. The problem of predicting inventory stock with fluctuating sales is a challenge, especially at the price we offer. Please consider the 220v VFD, even if a 220 outlet is needed to be installed. We have found that the 220v VFD units performance to be better than the 110v VFD units.

  • When we simulate cutting a part, the part is 40% larger than it should be. Why?

    What software are you using to simulate the CAM machining operations?

    Additional Information:
    I drew my part in ViaCad, opened part in CamBam to produce GCode, then Mach3 to simulate cutting part. Everything worked as it should but part was too large.

    Additional Information:
    It sounds like steps per unit is not calibrated properly. Use the Mach3 to calibrate the axes. In the settings tab, there will be axis calibration labeled just above the reset button. There is a button just just below axis calibration called set steps per unit. When the button is clicked, mach3 will present you with a dialog box asking for a measurement of how far to move the specific axis you need to calibrate (use a number that will not make the machine over run the axis). The machine will move to a certain length. Measure that length and enter it into the next dialog box that Mach3 presents to you. Do this for each axis.

  • WHEN SHOULD INFLUENZA (THE FLU) VACCINE BE GIVEN?

    You can begin offering vaccine as soon as vaccine becomes available. Early vaccination of children younger than age 9 years who are first time vaccinees can be helpful in assuring routine second doses before the influenza season begins.

  • None of the motors turn when activated in demo mode

    The motors could be wired incorrectly causing them to lock up. Make sure to check the wiring to make sure the X and Y are connected to the correct terminals.

  • Where are the limit switch connections made when the switches are in series, and NC??

    One end of the limit switch circuit will be connected to the pin and NC, and the other end will be connected to COM and GND.

    For example: (the "-" is wire.)

    [Breakout board input pin] ---- ([NC on switch] [com on switch]) ---- [NC on switch] [com on switch] ---- [back to GND on the breakout board]

    An explanation of the limit switch connections is located on the brakout board datasheet: https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay (instruction step # 1.

  • When will the #40 Collar/Sprocket Combo be available ?

    We are in the process of finding a replacement vendor. If you purchase the combo, we will ship it out as soon as we have them in stock. If you change your mind, or we do not find a suitable vendor, you will be able to get a refund.

  • When will Andre pay for his items?

    Try slowing your feedrate down and increasing spindle RPMs. End-mills will leave a poor finish if you go too fast. Make sure your cutting depth isn't too much. Maybe the endmill or cutter is blunt? Could it be the feed direction of the cutter? Some materials need to be fed in a certain direction.

  • When will you have the 4kw spindle package back in stock?

    We are depreciating the 4 kW spindle. The size of this spindle is very large and heavy and our supplier is not carrying them anymore. The 2.2 kW spindle is such a good spindle for power and size that the 4 kW spindle is overkill for most of how we use machine, and for the general market that we are in at the moment.

  • IS IT OK TO LEAVE THE VACUUM PRESSURE CONTROLLER PLUGGED IN ALL TIME WHEN PUMP SWITCHED OFF?

    I don't see anything in the datasheet for the relay that indicates an overheat condition. While the relay is engaged, the power consumption is 400 mW and I don't believe this is enough to raise the temperature faster than the heat dissipation from the metal on the leads through convection or radiation outside of the rated temperature working ranges providing that you maintain an ambient temperature range within -40°C to 85°C (with no icing or condensation).

  • When wiring NC limit switches in series to the V5 BOB where are the connections made on the BOB?

    The breakout board has input pins on one side. Use these pins to connect limit switches. The return of the circuit goes to gnd which is located on the same side, where the input pins are located.

  • When is the license for the software we purchased coming to us?

    Mach3 or Mach4 licenses purchased from us go through a process that includes us purchasing the license from the Mach3 developer first. The developer can take up to 2 hours to delver that license back to us to be emailed to the customer.

    If the license was purchased outside of business hours, then we will start the process at the beginning of the next business day.

    If you notice a delay in this process, please give us a call so we can provide a status, or let us know that you purchased the license so we can get the process going. Even during business hours, it may take some time to get to your order with our workload.

    Thanks.
