A Fortus drive block motor feeds filament from the canister to the print head, and it’s one of the more common wear parts on 360mc and 400mc machines.
Stratasys is saying one thing when it comes to repairing faulty drive blocks while Pivot AM Service is singing a completely different tune to the benefit of Fortus 360mc and 400mc owners. Here is the question and answer between a customer and Stratasys when asking Stratasys if they could replace a broken Drive Block Motor:
Question to Stratasys: We have issue with motor Faulhaber 2224U024S RL 0314 on drive block of Fortus 400mc. We need to replace motor in drive block. We received the following answer from Stratasys-
Stratasys answer: The motor alone is not available as a spare part. We only sell the whole filament drive, because some alignments are necessary to get the motor running correctly, which are not possible to do in the field.
Furthermore, I need to make you aware that the Fortus 400mc is off service since December 2024.
When the customer reached out to Pivot AM Service, our answer: don’t believe what Stratasys is saying in their response. We sell just the motor; the alignment comment is just a red herring. Even the Off Service comment is laughable; Pivot will be supporting these machines for years to come. Stratasys is just trying to force customers to trade in and upgrade. If you’re dealing with a similar motor or drive block issue, request a quote, and we’ll tell you straight whether it’s a simple part swap.
According to Pivot AM, yes. Stratasys told one customer that the motor alone was not available as a spare part and that only the complete filament drive could be sold, citing alignment requirements. Pivot AM sells the motor separately.
Pivot AM sells the individual drive block motor rather than requiring customers to purchase the complete filament drive assembly.
Stratasys told a customer that the Fortus 400mc has been off service since December 2024. Pivot AM disputes the implication that this means the machine can no longer be supported and states that it will continue supporting these machines for years to come.
A customer’s specific issue involved a Faulhaber 2224U024S RL 0314 motor installed in the drive block of a Fortus 400mc.
