I'm working on a checkbook program and I noticed that if you use a REAL field and store 1.00 into it it only stores the 1 so I just use text now to store numbers. JT On 4/22/2014 10:23 AM, Gene Heskett wrote: What sort of contortions are required to fully recover a number stored in SQLite as

Hi Guys, Here’s me nagging again about temperature, M106, M109, fan control etcetera. I’d like to know from you if/how you want to proceed with Additive Manufacturing and Machinekit. I’m running my Delta style machine with Machinekit and BeBoPr-Bridge, printing happily, no problems there.

Bas I have been following you posts on the temp control problem. I just though, why dont you sense the temp with an external device and then use a component to control the temperature. You could even use the pid component together with your own component. You could also sync the control with

Hi Jon http://www.pico-systems.com/acservo.html Ah, I see that would make thinks much easier. You COULD, in theory, run it with just the Direction signal in synchronous antiphase mode, but this may cause the filter inductors (and maybe the motor, too) to run hot. Our servo amp was

Hi Jon Andy Pugh suggested you could run my PWM servo amps with just ONE wire/output pin. That is what I was referring to, and that two wires would be better. Ah, OK. Got it. Thank for the clarification. With sign/magnitude control, there is no output until the PWM signal has pulses on
