At this time, I making the garage to put Mechmate and buying materials.(Many chip$) Can forgive my ignorance during and before the building with my questions. I prepared, in flickr, one account for place in the world the mechmates photographs. put your place is free and simple.

Good Luck Ros!
|
Ros wonderful, I have asked http://www.hepcomotion.com/index_es.htm budget and costs € 38 ($ 53,7) each bearing W3, I think I will get in touch with Superior Bearing Company.
|
Ros, sorry about the photo posting problems. I hope it is right now?
|
Thanks very much Gerald. The problem was that I accidentally deleted images.
Hi Paquintosh im very impressed with the Superior Bearings Quality, Recommend you this 100%. Paco, si estás en Madrid, puedes mirar por las zonas industriales a ver si encuentras buenos precios en material. Ya nos mostrarás imágenes de tus progresos. Regards. |

Mamba parts arrived
Today, the mamba parts arrived. The Quality is the best, im very happy with the results, Pressicion, service and price. The spider is perfect aligneed and bended, the laser cut is very clear. Attachment 5881 Attachment 5882 High quality kit image Attachment 5883 Total Costs in euros: 208€ + 105€ shipping Gerald, The Cutting company is very grateful with the quality of plans. Thanks!!! |
Ros,
A couple of things to watch out for, the upper little tab on your spider still has to be bent, you can do this with a hammer and vise. The second is that your Y car estop flange is bent at 90, it should only be 45. This can be easily fixed with a little muscle as well. My bender did that too on the first try. :) I see you also had your z slide plate laser cut, did you do up the cut file yourself? |
Ros, at my day job we sometimes spend €10 000 per month (per order) on laser cut steel. Every time the delivery arrives, I stand and look at it for a few minutes in amazement at what quality is received for the amount of money paid! :)
|
Ros, that company will have cut the material?
It is important, as will the plans of mechmate. And the price is right. ¿Qué empresa te ha cortado el material? Prefiero hablar con ellos porque ya tienen conocimiento de los planos de la MechMate. Y el precio es razonable. Sorry for my english |
Thanks Heath Im fix this, the Z plate is a dxf file im prepared with the Gerald Help, maybe not is the best steel for the Z plate, is the 50cm plate.
Ok Gerald, The company is big and i think hi know wen a work is fine. Hi !!! Paquintosh, I can sent you the company from Barcelona to you mail, their only work via telephone but receive the files via mail. Les puedes preguntar por el trabajo realizado recientemente para Canarias, seguramente tienen los datos en el correo aún, si no, los puedo reenviar, ya que los tengo preparados. Regards. |

Heath, the upper litte tab is bent :) see in this image.
Attachment 5901 And the file for the Z plate in dxf format: Attachment 5918 |
Ros,
Sorry, the other photo looked like it was unbent. Thanks for the file. :) Good luck. |

I have a problem with my spider.
Is 6mm smaller than the Y-Car. Attachment 7184 I'm thinking in add washers to complete the 6mm but this is one unstable solution |
That is not a problem . . . . . . a problem is when the spider does not fit in the Y-car! :)
Fill the space with washers or a plate of the correct thickness. |

But the distance between center points is perfect
Attachment 7191 And distance in the Y-Car is OK Attachment 7192 |
Dont worry Ros, it is designed that way, we have all added shims or washers to our assemblies. It also gives you the opportunity to adjust the spider to be 100% perpindicular to the table.
|
Thanks Gerald Alan.
yes, I'll put a plate of 6mm between the spider and the Y-Car. |
What can one do if it does not fit? I have assembled the Y car without welding it, and tried fitting the spider in, and it was not going to go in without force. I measured the distance between the inner sides of the y-car, and it is within specified limits, and the outer distance of the spider is also correct. I am scratching my head a bit.

The hole through the y-car is 200mm +/- the typical tolerance of a laser cutting company, which is about 0.1mm.
The max. width of the spider is 199mm (see drawing 10 40 432 B). You can get interference problems if: - the laser cutting is inaccurate (not very likely) - you increased the thicknesses of 10 40 432 (spider) and/or 10 30 455 (tower carrier) - the bending of 10 40 432 (spider) was not accurate. The solution is to increase the 45 degree bends of the the spider until it fits. |

I had the same issue, we where 'off' by about 1mm and we simply grinded 1mm of the spider, about 0.5mm on each side. In our case the problem started because we had plasma cut parts, teh spider was bend perfectly. Ries |
Cool, will try that. Am unfortunately at work in Kenya, so will only be back home mid jan. Keep well. Thanx for the advice.

Hi Ros
I saw your youtube video pop up in my google alert for "Mechmate" - the motors move so well done. My Mechmate is set up roughly the same in terms of drivers and motors. The Leadshine stepper motor drivers can be configured using a special serial cable and software called ProTuner. This process is just like tuning the gecko drivers but with the PC rather than a screw driver. Each motor is done one at a time. To tune the motors, get the cable and run the software. It then looks for the resonant frequencies that the motor has and smooths that out for you. Watch the protuner run and you will see that it runs the stepper motor through a range of RPM's to establish it's performance. Note the Protuner is run with the motor unloaded. After you have finished remember to save the setting to the drive. You can also use the software to set the the AMPS, microsteps and standstill current if the dip switches are set to allow you to do so. Hope I have made the two functions of the ProTuner software reasonably clear for you. Another type of "motor tuning" you might have read about in Mach3 is a further step that is additional to the two other functions I have outlined above. Keep up the good work. Regards Ross |

Thank Ross.
Interesting tool google alerts. Another think. I'm searching gears for my motors, for gear direct to the MotionKing 34HS9801 shaft.(14mm) In the search, im see the Chiaravalli here in Spain Gear catalog. Their have different module1 Gears with the dimensions near the DP20: Attachment 11038 Im thinking about the distances between A and B. If the MotionKing shaft is 14mm and the DP20 Gear is 16mm in B, it only give me 2mm when drill the A hole to 14mm. The question is, what distance between A and B is mechanically reasonable? Thanks. |
Gerald and others have established 3mm as the minimum.
Remember the grub screws retaining the pinions need to be tapped into this remaining thickness. Just use the 24 tooth pinion unless you are willing to sleeve the 20 tooth pinion with a metal ring. Regards Ross |
Ros, be careful here, a DP20 gear is not the same as a module 1 - 20 tooth. see this thread. You would need to go for a minimum of a 24 tooth Module 1 gear (20mm boss - 14mm hole = 3mm wall.
|
A DP20 gear with 20 teeth has a diameter C of 1inch = 25.4mm
A module1 gear with 24 teeth has a diameter C of 24mm The non-metric people use DP20 with 20 teeth, the metric people use module1 with 24 teeth - they are close the same to give diameters of 1 inch compared to 24 millimeter. |
