Re: How precise can your Smartrap print? - Alignment issues - 11 years ago
QuoteCellJeffe Quotecristian QuoteBackEMF I think it would be great to be able to slap together 3 axis and hit the print button, let the machine figure out the wonkeyness and spit out a perfect print. That woudl be great, but even after thinking about it for some time I cannot find ways to detect automatically skew. It may probably be detected without printing a calibration object by using some fby regpye - Smart_Rap

The music industry replaced the 12 inch records with MP3, now that was a bad idea i admit, but now there is FLAC and everyting is ok in that department.

Re: How precise can your Smartrap print? - Alignment issues - 11 years ago
QuoteBackEMF I do understand why some people would bounce it on 'bad hardware design' though i also see the advantages of having clever software solutions. And since autolevel already exists and the addition of this skew correction looks like it is only a small extra addition i don't see why it shouldn't be included. Actually it would be great if this somehow could be included IN the autolevelby regpye - Smart_Rap
Re: Noise reduction - 11 years ago
QuoteBackEMF Experimenting with feed rates and acceleration now, i hear differences in tone but not yet in loudness. I must find some good info on these settings how they relate to the motors and how the 2 settings work together / against each other. I hope i don't damage anything.

Re: New to 3d printing with smartrap need some help - 11 years ago
Quotesmartfriendz Would it be nice to have the smartrap in imperial ? i wonder.. No Way! About the only country using imperial is USA, nearly all other countries use metric. Imperial has some strange calculations to be made for 3D printing, not really easy to do like metric. I have no idea why USA has not gone metric yet, it makes it hard to fit in with the rest of the World.by regpye - Smart_Rap
Re: How precise can your Smartrap print? - Alignment issues - 11 years ago
Quotesmartfriendz Hi Christian, Thank you for those feedback. I can only agree with all that About the Z , I think that making a triangle would be the best too, with maybe two threaded rods going on the back , behind the steppers and attached on the top. That would make a solid triangle reducing the flexibility of those two smooth rods. It is that or using M12 smooth rods like in the ptrintby regpye - Smart_Rap

QuoteVDX ... look into the data-sheet, there should be a 5V input for activating the laser ... maybe even a 0-5V analogue input.

Re: Smartrap evolution, improvements... - 11 years ago
QuoteBackEMF Hmm, for some reason the Z axis is screeming especially during bedleveling. The small adjustments during a print are quiet. Around about line 375 in configuration.h file there should be a line that is similar to this v #define DEFAULT_MAX_FEEDRATE {500, 500, 2.5, 25} // (mm/sec) #define DEFAULT_MAX_ACCELERATION {1000,1000,50,500} // X, Y, Z, E maximum start speedby regpye - Smart_Rap

Re: Madmike8's Smartrap Build - 11 years ago
QuoteBackEMF I've got another interesting theory. Maybe there are differences in the encoders themselves. I will lookup some data-sheets and see if there are differences. Apart from this what i find most irritating is that in some menu's turning right the values increase and in others they decrease so no matter how you flip the values in pins.h there are always values that work the wrong way aroby regpye - Smart_Rap
