2:34 We always used some Loctite 273 to fix the bolts to the cabinet. So they don't come off. 8:35 flyback diode ? Will prevent the brake to close fast enough, so use a varistor instead. Brake will work much faster! 9:03 Battery backup! Normally you can turn the motor without loosing position counting. But if you remove the motor from the spindle, all is lost! So don't forget to write down, how and where to do homing! If you need it some years later, all is forgotten and lost in time... [Blade runner] 13:16 Yes homing against a fixed block is usual today anywhere, but I don't like it! I still think there's an overload to the ball bearing nut of the spindle, even with reduced currents, because of momentum! I prefer and recommend switches ! And I know how to use them, to bring all accuracy... 14:44 keyed shaft: You use them for conveyor belts mostly! If the motor is turning one direction only. But in a CNC with turning left and right, you will always see some tolerances in that key piece. Which will bring you faults if clamping isn't sufficient. So use sufficient clamping instead and get rid of that key piece! Great work though! Have fun

Nice to see some EtherCAT in a DIY application. For a hobby project, that's really impressive. The whole configuration and parameterisation with EtherCAT, especially if you want to drive DC synchronously, is a steep learning curve. I work for a company that manufactures servo amplifiers, motors etc. and I was a bit perplexed about the encoders. If they were "real" absolute encoders, they wouldn't need a battery to store their current position. To me, this smells more like normal incremental encoders that are battery-backed on the servo amplifier side. A proper multiturn absolute encoder quickly costs 5 to 10 times as much as a simple incremental encoder.
@varno
@varno 10 ай бұрын
It could be that, or it could be that it needs to count the total number of revolutions, an absolute positioning encoder can't determine 1.1 rotations from 2.1 rotations for example.
@bouni8506
@bouni8506 10 ай бұрын
I can't say how Leadshine does it but I know for sure how Omron does it. They have a Single Turn Absolute encoder built into their absolute servos, that way they can tell the exact position for one turn, additnally they count how many full turns the motor has made so far, which multiplies by the absolute encoder resolution plus the fraction of the current turn gives the absolute postion. With that the just need to update the memory for a full turn and hold that using the battery power. The newer series 1S is even fancier and doesn't need a battery at all. The use the energy generated by the rotation of the motor to update the absolute rotation counter. The only thing I don't know is what happens if a motor goes back an forth over the tipping point of a full turn by a few increments (does this generate enough energy to update the memory every time!?)

Single turn absolute encoders could use a battery for multi turn counting, but it's probably an incremental with drive side keeping track. And to the other person, you are describing a weigand sensor for multi turn counting. They dont use energy produced by the motor, they power themselves. Look up weigand effect.

Marco, layman's comment here; use lubrication when cutting aluminium. Otherwise your endmill chokes as an ultimate result. In the meantime your surface finish deteriorates. You can unclog your endmill using a strong base solution. But that doesn't correct your lost workpiece and heart damage when the endmill suddenly decides to hold position and kill all movement...

First of all, thank you very much for the entertaining video! Just a few little things that I noticed: 1. I would recommend that you fuse the secondary side of the power supply. In the best case, I would use a selectivity module or at least a semiconductor-based fuse. For example, the LOCC box from Lütze would be an option for you, as you don't have a lot of space in your control cabinet. Depending on your power supply's peak current, you can also use a normal circuit breaker to achieve a decent level of protection. 2. I would also recommend grounding the 0V directly at the power supply to detect and switch off short circuits of 24V wires against the housing. 3. Since you are from Germany, I would also recommend adapting the wire colors next time. according to EN 60204-1, red is for AC control circuits (24V DC in your case) and black for AC load circuits (0V DC in your case). It would be more correct to design the 24V wires in dark blue and 0V in dark blue / white or also in dark blue. Are you switching the STO via etherCat because your connector is not plugged into the servo drive?

@@reps Former industrial CNC field service engineer here. The practice with industrial cnc is either a constant force counterbalance or a servo motor large enough to handle the weight. counterbalance can either be a weight and chain system or a hydraulic cylinder with a fast acting counterbalance valve (actual product name). both of these counterbalances systems are used in relatively slow moving systems. For high speed and small rapid feeds, the motor only is the most common approach. Also,the vertical axis will sometimes use a lower pitch ballscrew. I see that your motors have a 3000rpm rated and 6000rpm peak, will a lower pitch work for you? An other consideration of Z-axis cut quality is the stiffness of the Ballscrew and the support bearings . Any amount of float will harm cut quality , and an incorrectly set up counterbalance will make it even worse . the counterbalance lift should always be less the the weight of the spindle assembly. Finally one of the most cute and clever counterbalance systems I have seen was installed on a sherline mill. A small bore air cylinder connected to a 2L plastic soft drink bottle . the system was charged with enough air pressure to acheive the desired balance , and because the 2L bottle is is both expandable and a much larger volume than the cylinder it is almost perfectly constant force and Zero inertia.

EtherCAT is a remoto I/O system which run on a 100 MBit network. What starts (and ends) with a normal network card by sending a ecat package what goes to all ecat modules ,in series, and then back to the same network card. The time delay is one bit (10 nS) per module. The outputs are set when the stream is coming by and the status of inputs is filled in (in the stream), so the returning message has all data of outputs and inputs.

Machining such ball shape with a ball end mill, means that the tool contact point moves from the side to the tip. And the surface speed of the cutter also goes from 100% to 0%. So without changing the rpm for every Z-step, the cutting speed is going to be out of the good range. This is where a 5-axis machine can help, since it can keep the contact point.

Isn't connecting the pneumatic valves directly to the Beckhoff input dangerous, since the valve are spools? You'd need an free-wheeling-diode right? Or is that included in the valves?
