Phidget Network Server Errors on Raspberry Pi 4

I'm running a Phidget Network Server in a Docket multi-container application and I'm seeing this on startup: 2020-04-14T15:00:35 <ERROR> phidget22 : ****************************** Logging Enabled ****************************** * Phidget22 - Version 1.6 - Built Mar 31 2020 18:37:30 * ****************...

Setting Acceleration with 1067

Good day, reader! I'm trying to rip out some custom ramping code and replace it by setting the acceleration on our stepper through the API. We've got the rescale factor set to drive off of RPM, so setting the velocity to 1 = 1 RPM. I'm a little bit confused by the language in the API documentation: ...

Reducing Voltage w/ 1067

Good day everyone! We've been running 12V rated motors with the 1067 and a 24V power supply for some time now. One of the things we noticed early on is that the motors get pretty hot. I don't have any current measurements but at one point I remember getting an IR reading of 70C. I noticed that there...

Current Output on 1067_0/B

Is there a way we can get the current output from the 1067_0/B boards? I'm currently using the javascript API.

Re: Measuring Voltage of a Thermistor Circuit

We know the circuit outputs < 5V under all conditions. We're not 100% on the voltage range but we've tested it thoroughly and are confident it will fall within the limits of the board. What wound up working was putting the data line in parallel on the grounded side of the thermistor. --- (-) (+) ---...

Measuring Voltage of a Thermistor Circuit

Good whatever-time-of-day-it-is, kind reader! We're trying to hook up a thermistor circuit for leak detection to an 8/8/8 interface kit and I'm wondering what the best way to go about this is. Essentially what we want to measure is voltage. The trick is that the thermistor needs to be heated with a ...

24VDC to PhidgetStepper 1067 w/ 12V Stepper

Our build is currently using a PhidgetStepper 1067 with a 24VDC supply which controls a third party stepper rated to 50V. We're looking to downsize the stepper footprint to something like this NEMA-23, which has a recommended 12V: https://www.phidgets.com/?tier=3&catid=24&pcid=21&prodid=...

Detecting Stall w/ PhidgetStepper 1067

We have a device with a stepper motor controlling a larger assembly which could jam under certain circumstances, especially during development phases where we're modifying geometry. I was wondering if there is a way with the 1067 to detect a motor stall? I'm sure we could rid up a second sensor to d...
